I was listening to a radio interview of a Donald Trump supporter this week, a former local Republican elected official in North Carolina. Asked why he supports the New York real estate developer, the man replied that Trump will solve the three biggest challenges facing our country: immigration, jobs and the national debt. We all know what Trump will do to end illegal immigration, and while he won't be specific on how he'll create jobs, he says in a 38-second video on his website he'll be the "greatest jobs-producing president that God ever created."

If you want more details on how he'll create "millions" of jobs, the only place to find them on the site is under "U.S.-China Trade Reform," because "Jobs" isn't on his list of six major policy areas. Trump says he will reclaim millions of American jobs and revive American manufacturing by putting an end to what he calls China's illegal export subsidies and lax labor and environmental standards. One way he wants to stop American companies from moving jobs overseas is to slap a 35 percent tax on goods coming into the U.S. produced by American companies who have moved offshore.

What Trump doesn't say is that raising tariffs on goods coming into America will raise not only the prices of those goods, but many other prices as well – and stop what little economic growth we have. "If Donald Trump's plans were ever implemented, the country would sink into a prolonged recession," former GOP nominee Mitt Romney said last week. He's right. Higher prices, inflation and rising unemployment would inevitably result, hurting poor and working class consumers the most.

And here's what Trump says he's going to do about the national debt: "One of the things I'm going to do – and largely with our great tax plan where everybody's taxes is [sic] going down – we're going to grow our economy. We have to get rid of the $19 trillion in debt. So unfair. So totally unfair to our young people. We are not going to leave you with that burden." That's it, 26 seconds long on video. That doesn't sound like a detailed plan for reducing the national debt to me.

Unfortunately, like "Jobs," you won't find "National Debt" listed at all among the six major policy areas listed on Trump's campaign website, but if you go to the "Tax Reform" section, you'll see he says his plan to reform our tax code is revenue neutral, and therefore doesn't add to the debt and deficit.

While his tax reform plan simplifies the tax code and reduces tax rates for individuals, Trump argues his across-the-board tax cuts "are fully paid for" by eliminating loopholes on the very rich, enacting a one-time 10 percent corporate tax rate for repatriated overseas cash and reducing corporate loopholes and the deductibility of business interest expenses.

But according to the nonpartisan Tax Policy Center, Trump's plan would increase our already massive national debt by $11 trillion by 2026, and increase it by 80 percent of GDP in the following decade. The Tax Foundation reaches a similar conclusion.

What Trump supporters need to know is that as the national debt climbs higher and higher, so will interest payments for the debt. According to the Simpson-Bowles Commission (a.k.a. The National Commission on Fiscal Responsibility and Reform), this will result in higher interest rates for all borrowers, both individuals and businesses. Anyone holding a mortgage or credit card debt or student loans will be affected, which will be millions of Americans. Private investment will be crowded out because it will be more expensive for entrepreneurs and businesses to raise capital and most importantly, create jobs. It's hard to see how Trump could create "millions and millions" of jobs under such a scenario.

Working-class voters who like that Trump sticks it to the "elites" might want to know that his across-the-board tax cuts benefit high-income taxpayers the most. In fact, the Tax Policy Center reports that middle-class households would receive an average tax cut of $2,700, or 4.9 percent of after-tax income; the highest 0.1 percent of taxpayers (those with incomes over $3.7 million) would get an average tax cut of more than $1.3 million in 2017, or nearly 19 percent of their after-tax income.

The biggest problem with Trump's plan is that while he says he's in favor of a balanced budget amendment, there's not a single mention of any federal spending cuts – or even any spending restraint. No mention of reforming Medicare or Social Security, the two biggest drivers of federal spending.

Keep in mind that when Franklin D. Roosevelt established Social Security, the average life expectancy was 63 years and Social Security payments began at age 65. Today the average life expectancy is 70, and Social Security payments can start as early as age 62. As a result, both Social Security and Medicare are quickly running out of money.

As baby boomers retire and spend more on health care costs, the debt will cause even more problems. According to the Simpson-Bowles Commission's projections under current law – not even under Trump's plan, which would make it far worse – interest on the debt could rise to nearly $1 trillion by 2020, only four years from now.

Those mandatory interest payments will squeeze out funding for all other government programs. In fact, by 2025 tax revenue will cover only interest payments on the debt, Medicare, Medicaid and Social Security. All other government programs – education, transportation, infrastructure, even national defense, veterans benefits and homeland security – will have to be cut or paid for with even more borrowed money and higher taxes.
