Freed slaves were NEVER PROMISED 40 acres and a mule. An abolitionist Congressman suggested it as a New Dealish way to get the freedmen on their feet. He ended up being assaulted by a Congressman from S. Carolina--with a cane.
Everyone likes to whine about the "benefits" (if that's what you want to call them) that Native Americans receive. Most of these people have probably never been on a reservation, where they can see for themselves the poor conditions our country calls "subsidies" for Native Americans. Alcoholism, domestic violence, illiteracy, and crime are RAMPANT. The same people who complain about Native Americans receiving reduced prices in housing, education, and other social goods (hey, after the HORRIBLE treatment Natives receieved in their OWN LAND, the government almost owes it to them) are no doubt the same people who think that if affirmative action weren't in place, they would have gotten into law school/been hired/gotten that home loan.
And why should Russell Simmons, or any PRIVATE CITIZEN, be obligated to give money to anyone? You don't see Donald Trump doling out funds to Appalachia, do you?
The government created the ghettoes--and it's their responsibility to something about them.
