As soon as President Barack Obama called on Congress to raise the minimum wage to $9 an hour in his State of the Union address last week, you could see Speaker John Boehner, seated behind the president, uttering his religious mantra: “Job killer.” And even if you couldn’t read his lips, you could read his mind: “Campaign contributions.” He and his Republican colleagues could expect huge donations from business lobby groups – especially those that depend on low-wage workers, like the hotel industry, restaurants and fast-food chains, nursing homes and hospitals and big-box retailers – to keep Congress from embracing Obama’s modest proposal.

Boehner’s “job killer” grumble should come as no surprise. Business groups and their political allies have been “crying wolf” about the minimum wage ever since President Franklin D. Roosevelt proposed it during the Depression to help stimulate the economy. The critics warned that enacting a minimum wage would destroy employees’ drive to work hard and would force many firms out of business. The minimum wage law, warned the National Association of Manufacturers (NAM) in 1937, “constitutes a step in the direction of communism, bolshevism, fascism, and Nazism.” Congressman Edward Cox, a Georgia Democrat, said that the law “will destroy small industry.” These ideas, Cox claimed, “are the product of those whose thinking is rooted in an alien philosophy and who are bent upon the destruction of our whole constitutional system and the setting up of a Red Labor communistic despotism upon the ruins of our Christian civilization.” Roosevelt and most members of Congress ignored these warnings and adopted the Fair Labor Standards Act in 1938, establishing the federal minimum wage of 25 cents an hour.

Since then, each time Congress has considered raising the minimum wage, business groups and conservatives have repackaged the same arguments. In 1945, NAM claimed that, “The proposed jump from an hourly minimum of 40 to 65 cents at once, and 70 and 75 cents in the following years, is a reckless jolt to the economic system. Living standards, instead of being improved, would fall – probably to record lows.” Instead, the next three decades saw the biggest increased in living standards in the nation’s history.

In 1975, economist Milton Friedman, a conservative guru, said: “The consequences of minimum wage laws have been almost wholly bad, to increase unemployment and to increase poverty. In my opinion there is absolutely no positive objective achieved by minimum wages.” While campaigning for president, Ronald Reagan said, “The minimum wage has caused more misery and unemployment than anything since the Great Depression.” In 2004, David Brandon, the CEO of Domino’s Pizza, declared: “From our perspective, raising the minimum wage is a job killer.” Earlier this month, Jason Riley, a Wall Street Journal editorial writer, called the minimum wage a “proven job killer” on the newspaper’s cable talk show.

Following Obama’s State of the Union address, business representatives and conservative media pundits echoed the same talking points. Analyzing Obama’s speech for Fox News, Nina Easton, an editor for Fortune magazine, repeated the claim that increasing the minimum wage is a “job killer.” Michael Saltsman, research director at the business-backed Employment Policies Institute, told Fox Business News that “minimum wage hikes lead to job losses.” Bill Herrle, executive director of the National Federation of Independent Business’ Florida affiliate, told Sunshine State News that Obama’s plan was a “job killer.”

But such dire predictions have never materialized. That’s because they’re bogus. In fact, raising the minimum wage is good for business and the overall economy. Why? Because when poor workers have more money to spend, they spend it, almost entirely in the local community on basic necessities like housing, food, clothing and transportation. When consumer demand grows, businesses thrive, earn more profits, and create more jobs. Economists call this the “multiplier effect.” According to Doug Hall of the Economic Policy Institute, a minimum wage hike to $9 would pump $21 billion into the economy. Moreover, since most minimum wage jobs are in “sticky” (immobile) industries – such as restaurants, hotels, hospitals and nursing homes and retail stores – that can’t flee overseas, raising the level doesn’t lead to job flight. Not surprisingly, the National Restaurant Association is, along with the US Chamber of Commerce, one of the fiercest opponents of a minimum wage hike.

In recent years, the nation’s job growth has been concentrated in low-wage sectors, led by Walmart, the nation’s largest private employer, whose pay levels are so low that many employees are eligible for food stamps.

More than one-quarter of all jobs pay poverty-level wages. According to a National Employment Law Project study, the majority of new jobs created since 2010 pay just $13.83 an hour or less. This has contributed to the nation’s widening economic inequality. Nobel laureate economist Joseph Stiglitz recently said, “Increasing inequality means a weaker economy” for all of us.

Meanwhile, of course, the incomes of the wealthiest Americans – including the corporate CEOs who lobby against raising the minimum wage – have skyrocketed. Since 1993, the incomes of the richest 1 percent of Americans increased by 57.5 percent, while the incomes of the bottom 99 percent increased by only 5.8 percent, according to studies by economist Emmanuel Saez at the University of California at Berkeley. Since 2009, as the country was emerging from the recession, the wealthiest one percent saw their incomes grow by 11.2 percent while the rest of Americans watched their incomes shrink by 0.4 percent. In other words, the richest 1 percent – those with incomes over $600,000 – captured almost all of the income gains in the first two years of the recovery.

The last time Congress raised the federal minimum wage was in 2007, when President George W. Bush reluctantly signed the bill passed by the Democratic Congress to raise the federal minimum wage from $5.15 an hour (where it had stood for ten years) to $7.25 an hour (phased in over several years). It has remained at $7.25 since 2009. A full-time worker who earns the current minimum wage makes only $15,080 a year. According to “Out of Reach,” a report sponsored by the National Low-Income Housing Coalition, in no state can an individual working full time at the minimum wage afford an apartment for his or her family.

In fact, the minimum wage has fallen in value because Congress hasn’t raised it to keep up with inflation. At its peak in 1968, the minimum wage was equal to about $10.50 an hour in today’s dollars. That’s a 25 percent decline in buying power.

Frustrated by Congress’ intransigence, a growing number of states have made an end run around Washington. Nineteen states now have minimum wages over $7.25 an hour. The highest is in Washington State, where the minimum wage is $9.19 an hour.

Cities, too, have enacted laws raising pay for low-wage workers. In 2003, Santa Fe, New Mexico adopted a citywide $8.50 an hour living-wage law with regular cost-of-living increases. At the time, Sam Goldenberg, a business leader, predicted that the law “would be a disaster for the businesses in Santa Fe.” And restaurateur Al Lucero called the plan economically irresponsible and argued that “people will be so content with $8.50 or $10.50 an hour that they’ll have no desire to improve themselves.”

Nearly 10 years later, Santa Fe has one of the lowest unemployment rates in the state at 5.1 percent. Jeff Mitchell, a senior research scientist at the University of New Mexico’s Bureau of Business and Economic Research, found “no evidence of adverse effects” from the wage hike. Santa Fe’s tourism industry is doing fine. Travel + Leisure magazine last year listed Santa Fe in its top 10 US and Canadian travel destinations for the 11th consecutive year.

In 2003, San Francisco voters also adopted a citywide minimum-wage law. The Golden Gate Restaurant Association called it a job killer that would “bankrupt many restaurants.” The Association of Realtors said that many hospitality industry workers were “likely to receive pink slips and join the ranks of the unemployed.”

Wrong again. A 2007 study by University of California economists found that after San Francisco’s minimum wage went up, restaurant growth was higher in the city than in neighboring East Bay cities. In December 2012, the city’s unemployment rate was 6.5 percent, well below the statewide average, and job growth in bars and restaurants has led the region’s post-recession recovery.

In November, voters in Albuquerque and San Jose passed ballot measures that will raise the minimum wage for workers in those cities. Albuquerque’s citywide minimum wage rose from $7.50 to $8.50 per hour last month and will automatically adjust in future years with inflation. In San Jose, the minimum wage will increase from $8 per hour – the current minimum wage in California – to $10 per hour starting next month and will adjust automatically in future years to keep pace with the rising cost of living.

Since 1994, about 200 cities have passed “living wage laws” that set minimums for workers for private companies that have municipal contracts, get local tax breaks or rely on city facilities. In November, for example, voters in Long Beach, California passed a ballot measure that raises the minimum wage for hotel workers in that tourist city to $13 per hour and guarantees hotel workers five paid sick days per year. A recent study by William Lester of the University of North Carolina and Ken Jacobs of the University of California-Berkeley found no difference in employment levels between comparable cities with and without living wage laws. They disproved the claim by that these laws drive away business or lead to reduced employment.

Most Americans agree that workers who toil full time shouldn’t be stuck in poverty. According to a national poll conducted last year, almost three-quarters (73 percent) of Americans support increasing the minimum wage to $10 per hour and indexing it to inflation. The same poll showed 50 percent of Republicans and 74 percent of Independents favoring an increase in the minimum wage. Majorities of every major religious group support raising the minimum wage to $10. Sen. Tom Harkin (D-Iowa) and Rep. George Miller (D-California) have been working on a proposal to raise the minimum wage to $10.10 indexed to inflation.

In his State of the Union address, Obama proposed to gradually raise the minimum wage so that it hits $9 an hour in 2015. “Let’s declare that in the wealthiest nation on earth, no one who works full time should have to live in poverty,” he said. In fact, a full-time employee earning $9 an hour would make about $18,720 a year, slightly below the official poverty level of $19,530 for a family of three. Under Obama’s plan, at least 15 million workers would directly benefit from a higher minimum wage. Millions more would get pay raises as the entire wage scale moves up.

Corporate America and Congressional Republicans are particularly upset that Obama’s plan includes a cost-of-living adjustment, which would automatically increase the minimum wage each year to adjust for inflation. Most businesses don’t like the idea of having to give employees regular pay hikes. And the Republicans hate the idea because it would eliminate their ability to keep the wage flat by refusing to raise it legislatively. Ten states – Arizona, Colorado, Florida, Missouri, Montana, Nevada, Ohio, Oregon, Vermont and Wisconsin – include a cost-of-living adjustment in their minimum wage laws. Since 1975, Social Security has had an automatic cost of living adjustment for benefit levels.

Although the evidence supports the advocates of a higher minimum wage, the battle to raise the federal minimum wage won’t be easy, because business lobby groups have put enormous pressure on members of Congress to resist this common sense policy. In addition to pouring big bucks into campaign contributions and lobbying, they’ve also paid huge sums to conservative economists and business-sponsored think tanks like the American Enterprise Institute to come up with misleading arguments about why giving Americans a raise is a bad idea. They generally argue that a minimum wage increase will particularly hurt small businesses – a view that the media often repeat with misleading anecdotes.

For example, the day after Obama’s State of the Union speech, NPR interview a California restaurant owner (who now pays workers the state’s $8 per hour minimum) who claimed that he’d have to lay off employees or cut back their hours if Congress raised the federal minimum wage to $9. But while this may be true of a handful of small businesses, the overall impact of lifting the minimum wage is good for business. Restaurants may have to slightly increase their payroll expenses, but they’ll benefit when customers have more money to spend, thanks to a minimum wage increase.

Indeed, contrary to business rhetoric, studies reveal that that higher minimum wage levels do not force employers to lay off workers. In a study published in the Review of Economics and Statistics, economists Arin Dube, William Lester and Michael Reich compared counties adjacent to state borders, where one state raised the minimum wage and another did not, between 1990 and 2006. They found conclusively that raising the minimum wage had no impact on employment. A similar study by Alan Krueger – now the head of the Council of Economic Advisers – came to the same conclusion. The Obama White House also noted that Costco, the retail discount chain, Stride Rite, a children’s shoe chain, and other firms have supported increasing the minimum wage, saying it reduces employee turnover and improves workers’ productivity.

These positive arguments won’t stop business lobby groups and Republican leaders from trying to block President Obama’s modest proposal. Speaker Boehner, who opposed the last minimum wage boost in 2006 when the Democrats controlled the House, said this week, “When you raise the price of employment, guess what? You get less of it…. Why would we want to make it harder to small employers to hire people?” Sen. Marco Rubio of Florida, who delivered the Republicans’ response to Obama’s State of the Union address, said “I don’t think a minimum-wage law works,” on “CBS This Morning.”

But if democracy is about translating public opinion into public policy, Americans are overdue for a raise. Increasing the minimum wage to $9 an hour and tying it to the cost of living will not, on its own, lift the country out of its economic doldrums. But it will definitely lift millions of Americans out of poverty, stimulate the economy, and create new jobs. It is the right thing to do both morally and economically.
