If the "free-market" theories of Ayn Rand and Milton Friedman were correct, the United States of the last three decades should have experienced a golden age in which the lavish rewards flowing to the titans of industry would have transformed the society into a vibrant force for beneficial progress.
After all, it has been faith in "free-market economics" as a kind of secular religion that has driven U.S. government policies -- from the emergence of Ronald Reagan through the neo-liberalism of Bill Clinton into the brave new world of House Republican budget chairman Paul Ryan.
By slashing income tax rates to historically low levels -- and only slightly boosting them under President Clinton before dropping them again under George W. Bush -- the U.S. government essentially incentivized greed or what Ayn Rand liked to call "the virtue of selfishness."
Further, by encouraging global "free trade" and removing regulations like the New Deal's Glass-Steagall separation of commercial and investment banks, the government also got out of the way of "progress," even if that "progress" has had crushing results for many middle-class Americans.
True, not all the extreme concepts of author/philosopher Ayn Rand and economist Milton Friedman have been implemented -- there are still programs like Social Security and Medicare to get rid of -- but their "magic of the market" should be glowing by now.
We should be able to assess whether laissez-faire capitalism is superior to the mixed public-private economy that dominated much of the 20th Century.
The old notion was that a relatively affluent middle class would contribute to the creation of profitable businesses because average people could afford to buy consumer goods, own their own homes and take an annual vacation with the kids. That "middle-class system," however, required intervention by the government as the representative of the everyman.
Beyond building a strong infrastructure for growth -- highways, airports, schools, research programs, a safe banking system, a common defense, etc. -- the government imposed a progressive tax structure that helped pay for these priorities and also discouraged the accumulation of massive wealth.
After all, the threat to a healthy democracy from concentrated wealth had been known to American leaders for generations.
A century ago, it was Republican President Theodore Roosevelt who advocated for a progressive income tax and an estate tax. In the 1930s, it was Democratic President Franklin Roosevelt, who dealt with the economic and societal carnage that under-regulated financial markets inflicted on the nation during the Great Depression.
With those hard lessons learned, the federal government acted on behalf of the common citizen to limit Wall Street's freewheeling ways and to impose high tax rates on excessive wealth.
So, during Dwight Eisenhower's presidency of the 1950s, the marginal tax rate on the top tranche of earnings for the richest Americans was about 90 percent. When Ronald Reagan took office in 1981, the top rate was still around 70 percent.
Greed was not simply frowned upon; it was discouraged.
Put differently, government policy was to maintain some degree of egalitarianism within the U.S. political-economic system. And to a remarkable degree, the strategy worked.
The American middle class became the envy of the world, with otherwise average folk earning enough money to support their families comfortably and enjoy some pleasures of life that historically had been reserved only for the rich.
