Alex Pfeiffer found this reporting mishap and relayed it to us it at The Washington Post Thinks Reporting On A Study That Shows Illegals Take Jobs Is Racist.
Steve Bannon is one of the current victims of the left using Saul Alinsky's tactic of freezing, personalizing and polarizing a target. He's been accused of every ism in the book. And according to the above cited article, Washington Post attempted to find evidence that Breitbart news was white-supremist. The articles WaPo found were about immigration studies and seminars that supported the theory that immigration of less educated workers had a negative impact on employment. You can follow the link for more details about those alleged connections to racism.
Borjas took the statistics coming out of the Mariel boatlift to determine what impact that influx of immigrants had on the local population. What he found most significant was the negative impact on the demographic group that most resembled the immigrants, specifically, high-school dropouts. This goes against the conventional wisdom that immigration has such a beneficial impact on an economy that everyone benefits. Wrong. It's merely redistribution.
For an excellent review of Borjas' book, "We Wanted Workers," see The Facts on Immigration.
And to anyone who thinks talking about this is racist, get a life that doesn't revolve around slandering those with whom you disagree.
