here a nice chart
A lot of the income of the top 1% of Americans comes from abroad. Nearly all big corporations are multi national. The left are untrustworthy liars, they deliberately try and cover up the huge increases in the wages of Chinese, Koreans and others since 1979. Of course your average American leftie college professor doesn't care that the so called Capitalist systems has pulled billions out of poverty in recent decades, he she is only interested in feeding their narcissistic Marxist fantasies. Its like did the Marxists of the Soviet Union or their droollng middle class fan boys and girls in the West care that six million working people were starved to death in the Holdomor? Of course not they only cared about their theocratic Marxist identity politics.
