Many believe that poor people deserve to be poor because they're lazy. As Speaker John Boehner has said, the poor have a notion that "I really don't have to work. I don't really want to do this. I think I'd rather just sit around."
In reality, a large and growing share of the nation's poor work full time -- sometimes sixty or more hours a week -- yet still don't earn enough to lift themselves and their families out of poverty.
It's also commonly believed, especially among Republicans, that the rich deserve their wealth because they work harder than others.
In reality, a large and growing portion of the super-rich have never broken a sweat. Their wealth has been handed to them.
The rise of these two groups -- the working poor and non-working rich -- is relatively new. Both are challenging the core American assumptions that people are paid what they're worth, and work is justly rewarded.
Why are these two groups growing?
The ranks of the working poor are growing because wages at the bottom have dropped, adjusted for inflation. With increasing numbers of Americans taking low-paying jobs in retail sales, restaurants, hotels, hospitals, childcare, elder care, and other personal services, the pay of the bottom fifth is falling closer to the minimum wage.
At the same time, the real value of the federal minimum wage is lower today than it was a quarter century ago.
In addition, most recipients of public assistance must now work in order to qualify.
Bill Clinton's welfare reform of 1996 pushed the poor off welfare and into work. Meanwhile, the Earned Income Tax Credit, a wage subsidy, has emerged as the nation's largest anti-poverty program. Here, too, having a job is a prerequisite.
The new work requirements haven't reduced the number or percentage of Americans in poverty. They've just moved poor people from being unemployed and impoverished to being employed and impoverished.
While poverty declined in the early years of welfare reform when the economy boomed and jobs were plentiful, it began growing in 2000. By 2012 it exceeded its level in 1996, when welfare ended.
At the same time, the ranks of the non-working rich have been swelling. America's legendary "self-made" men and women are fast being replaced by wealthy heirs.
Six of today's ten wealthiest Americans are heirs to prominent fortunes. The Walmart heirs alone have more wealth than the bottom 40 percent of Americans combined.
Americans who became enormously wealthy over the last three decades are now busily transferring that wealth to their children and grand children.
The nation is on the cusp of the largest inter-generational transfer of wealth in history. A study from the Boston College Center on Wealth and Philanthropy projects a total of $59 trillion passed down to heirs between 2007 and 2061.
As the French economist Thomas Piketty reminds us, this is the kind of dynastic wealth that's kept Europe's aristocracy going for centuries. It's about to become the major source of income for a new American aristocracy.
The tax code encourages all this by favoring unearned income over earned income.
The top tax rate paid by America's wealthy on their capital gains -- the major source of income for the non-working rich -- has dropped from 33 percent in the late 1980s to 20 percent today, putting it substantially below the top tax rate on ordinary income (36.9 percent).
If the owners of capital assets whose worth increases over their lifetime hold them until death, their heirs pay zero capital gains taxes on them. Such "unrealized" gains now account for more than half the value of assets held by estates worth more than $100 million.
At the same time, the estate tax has been slashed. Before George W. Bush was president, it applied to assets in excess of $2 million per couple at a rate of 55 percent. Now it kicks in at $10,680,000 per couple, at a 40 percent rate.
Republicans now in control of Congress want to go even further. Last Friday the Senate voted 54-46 in favor of a non-binding resolution to repeal the estate tax altogether. Earlier in the week, the House Ways and Means Committee also voted for a repeal. The House is expected to vote in coming weeks.
Yet the specter of an entire generation doing nothing for their money other than speed-dialing their wealth management advisers is not particularly attractive.
It puts more and more responsibility for investing a substantial portion of the nation's assets into the hands of people who have never worked.
It also endangers our democracy, as dynastic wealth inevitably and invariably accumulates political influence and power.
Consider the rise of both the working poor and the non-working rich, and the meritocratic ideal on which America's growing inequality is often justified doesn't hold up.
That widening inequality -- combined with the increasing numbers of people who work full time but are still impoverished and of others who have never worked and are fabulously wealthy -- is undermining the moral foundations of American capitalism.
