No one cares for the black people more than college-educated white Democrats.

I know, right?

So that’s why when educated whites move into America’s most tolerant, progressive Democratic cities, blacks move out, according to Eric Tang in the Washington Post.

Between 2000 and 2010, cities like Austin, Chicago, Washington D.C., San Francisco—places that vote majority Democrat, consider themselves socially and culturally progressive, and boast racial diversity—all lost unprecedented numbers of African Americans. San Francisco, for instance, saw a staggering 20.4 percent loss in its African American population between 2000 and 2010. Chicago and Washington D.C. also experienced double-digit losses.

Tang, an assistant professor at University of Texas, Austin, cites Stanford University research showing that as college grads become a bigger share of a Democrat-dominated city’s workforce, income inequality rises, driving out (often black) lower-wage folks.

Meanwhile, 100 percent of the big cities that Mitt Romney won in 2012 (ok, there aren’t many of them) saw their black populations grow — big time.

During that same decade, the only three major cities (populations over 500,000) that voted Republican in the 2012 presidential election— Phoenix, Fort Worth, and Oklahoma City—all saw significant increases in African American numbers; their African-American populations grew by 36.1 percent, 28 percent and 11.4 percent respectively.

Austin, known in Texas as “the blueberry in the tomato soup,” is unique among major cities in that it’s growing, but not in diversity. The actual number of black Austin residents decreased from 2000-2010 by 5.4 percent.

All of this proves at least two things:

1) reducing diversity makes the Democrat ideal of tolerance more achievable, and

2) while white Democrats may be college educated, blacks who pack up and leave are just plain smart.
