The U.S. economy is still sputtering. (See GDP growth chart above.)

Why is growth so slow and weak?

One reason is that average American consumers, who account for the vast majority of the spending in the economy, are still strapped.

The reason average American consumers are still strapped, meanwhile, is that America's companies and company owners — the small group of Americans who own and control America's corporations — are hogging a record percentage of the country's wealth for themselves.

In the past five years, American corporations have boosted their profits and share prices by cutting costs (firing people) and buying back stock. As a result, unemployment remains high. And wage growth for the Americans who are lucky enough to be working has been pathetic — the slowest since World War II.

Meanwhile, America's corporations and their owners have never had it better. Corporate profits just hit another all-time high, both in absolute dollars and as a percent of the economy. And U.S. stocks are at record highs.

Even Scrooge would be appalled. Many people seem confused by this juxtaposition. If corporations and shareholders are doing so well, why is the economy so crappy?

The answer is that one company's wages are other companies' revenues. Americans save almost nothing, so every dollar we earn in wages gets spent on products and services (including, in some cases, those of the companies we work for). The less that American companies pay their workers, the less American consumers have to spend. And the less American consumers have to spend, the slower the economy grows.

This isn't a complex concept. We're all in this together. People make it complicated by casting it as a political issue and inflaming partisan tensions. But it has nothing to do with politics.

Importantly, it doesn't have to be this way.

There's no "law of capitalism" that says that companies have to pay their employees as little as possible. There's no law of capitalism that says companies have to "maximize short-term profits." That's just a story that America's owners made up to justify taking as much of the company's wealth as possible for themselves.

Ironically, this short-term greed on the part of America's owners is most likely reducing their long-term wealth: Companies can't grow profits by cutting costs forever, because their profits can't grow higher than their revenues. At some point, revenue growth needs to accelerate. But that won't happen until companies start sharing more of the wealth they create with the folks who create it — their employees.

Let's go to the charts ...

1) Corporate profit margins just hit another all-time high. Companies are making more per dollar of sales than they ever have before. (Some people are still blaming economic weakness on "too much regulation" and "too many taxes." That's crap. Maybe little companies are getting smothered by regulation and taxes, but big ones certainly aren't. What they're suffering from is a myopic obsession with short-term profits at the expense of long-term value creation.)

One reason is that companies are paying employees less than they ever have as a share of GDP. And that, in turn, is one reason the economy is so weak: Those "wages" represent spending power for consumers. And consumer spending is "revenue" for other companies. So the profit obsession is actually starving the rest of the economy of revenue growth.
