Its true, but its not just about land its about resources.
Look at Detroit with its regional control with water now instead of it being just Detroit. That was a major reason why Flint got so fukked over because the last thing the wanted was the best water treatment in the hands of Detroit voters (i.e. Black folks)....
But don't just look at your neighbors for the answers, look at your successful aunts, uncles, cousins, siblings who all moved out to the burbs and took all their money (power) out of the cities and left the cities devastated.
In middle class black folks desire to keep up with white folks they opened the door to all this...we HAD power in many of our cities and we gave it up the minute we bought into suburban life....
Virtually EVERY civil engineer will tell you suburban life is practically unsustainable with a failing city center, so when we moved out there in the 90's we started (or at least exacerbated) the death knell.
If the government wanted to, they could fix things in every major city in 5 years. They just don't want to. Guilliani wanted white folks visiting new york to feel safe so he flipped manhattan in record breaking times.
Black people leave black communities because there are very REAL dangers to raising children in them.
1. Not having state funds regardless of income.
2. Not being able to get a loan regardless of credit.
3. police arresting your IVY LEAGUE son simply because he is black and in the neighborhood where cops have free reign.
4. shytty ass public schools.
5. Homelessness and the crime that comes with it.
6. Not being able to have control over the police force recruitment or budget (due to low black voter turn out because of systemic disenfranchisement. 25% of all black males have been to prison in their lives,.)
When history proves that no matter how much the black community proves themselves, whites will not allow them to be successful, the best defense is a got damn offense.
As the Vietnamese said when they beat the fukk out of the americans even though they were severely outgunned, outmanned, and outresourced....
"Grab them by their belt straps."
You can't systematically crush black people unless they are seperated. If they are right in those communities, they can't be obliterated by the constant shelling of the black community in fear of blowing away whites as well.
White flight is not as rampant as it once was so blacks are taking every chance they can to assimilate into communities where the government helps, not hurts them.
