What a biased bunch of BS that article is - if most middle and lower class wage earners salaries have remained flat for say forty years, and the top few percent have increased greatly, it sure ain't taxes that are the cause. Consider executive pay and then consider wage earner pay, look at Walmart as an example. The reasons for wage inequality require no wild ass assumptions, they stare you in the face. Lack of unions and outsourcing are sources, but so are old fashioned concepts like greed and self interest. What CEO should make millions while those who create the product, both at the engineer and production worker level get little or nothing and are threatened with the door for noticing the wide gap. Someone oddly immoral is wrong when nonsense like the OP is accepted and published as if some kernel of truth were contained in it.
"Average household income before taxes grew in real terms by nearly one-third between 1979 and 1997, but that growth was shared unevenly across the income distribution. The average income for households in the top fifth of the distribution rose by more than half. In contrast, average income for the middle quintile climbed 10 percent and that for the lowest fifth dropped slightly. Furthermore, income growth at the very top of the distribution was greater yet: average income in 1997 dollars for the top 1 percent of households more than doubled, rising from $420,000 in 1979 to more than $1 million in 1997." [Congressional Budget Office, Chapter One]

"As Jason DeParle reported recently in The Times, new research indicates that if you start off near the bottom of the income ladder in the United States, you’re far more likely to remain there than if you’re in the same situation in Canada or Europe. And if you start off poor in Denmark or Britain, for example, you’re much more likely to reach the top fifth in income than if you try to make the same climb in the United States. It seems that the Danish Dream and the British Dream are currently more alive — at least for the most disadvantaged — than the American Dream."

The irony of the Cold War's capitalism vs. communism paradigm is that capitalism in the US and other western countries required generous helpings of socialism to make it work. Conservative politicians like Eisenhower and Nixon seemed to understand this and generally supported the social programs listed above."
