Blacks overwhelmingly support the politicians that have authored the financial destruction of the American economy: Dodd, Frank, Clinton, Fannie Mae executives like Johnson and Raines, ACORN and so on.
The policies that destroyed the US housing market were an attempt to give a special preference to minorities who were not creditworthy enough to purchase their own home and carry a mortgage.
When the long period of housing price rises came to an end, the whole edifice collapsed, revealing the destruction of trillions of dollars of our national wealth.
What if blacks constituted a majority of the population, and the politicians they voted in at 80-90% had a hammerlock on power?
The United States would be an economic wasteland with corrupt socialist or communist politicians ruling over a dungheap and their supporters living off the breadcrumbs the politicians manage to throw their way.
I would add that if we were ever able to somehow move black support for the Democrat party from the 80-90% level down to even 60% support for the Democrat party, that would make ALL the difference in the world for the future of the country.
It would be the difference between a future of a prosperous and free country versus a country in permanent economic depression and decline.
