The Big Picture Lesson of the 20th century was that capitalism works and socialism and communism don’t. The rest of the world learned that lesson far better because they and their close neighbors suffered far more with the socialist and communist progeny of Saul Alinsky’s first radical. But America should know better because it has enjoyed most the workers paradise of capitalism.
Yet those who call themselves Progressive, a polite, Americanized word for Marxist, refuse to accept that obvious conclusion. That is why our politics have become so nasty. The Progressives know they can’t win a debate based on reason. So they turn to name calling, demonization, ostracism, anything to distract from and avoid a reasoned debate. Hence the widespread use of the term “dumbass” by pot smoking hippie Progressives in commenting on the reasoning of careful scholars that they disagree with, or the ubiquitous allegations that anyone who disagrees with them is lying, or bought off.
