What caused the wealth gap? (in the US over the past 30+ years)

So it’s not really Wall Street and big banks which are the source of our econmic problems, it’s globalization.

From http://news.salon.com/2011/10/11/what_caused_the_wealth_gap/:

“for most of American society, and certainly for the majority of Americans who don’t have a bachelor’s degree, globalization has meant facing much lower-wage workers abroad and increasingly powerful competitive pressures. So our society began to separate between the “haves” and the “have-nots,” really in the early 1980s.”

And paraphrasing: Ronald Reagan’s solution to the problem (less government), completely missed the point and, in fact, made things worse.
