Segregation is defined as "the enforced separation of different racial groups in a country, community, or establishment". At least it used to be defined that way.
When used under the original definition, it meant something akin to "apartheid". Blacks were not allowed in the front seats of buses, could not eat in white restaurants, had "separate but equal" schools, had special "colored" water fountains. All enforced by state and local laws. People of mixed race were seen as aberrations, and marrying someone of another race was illegal in some states. These laws were strictly enforced.
Up until the 1960's - when some brave people finally stood up and refused to be treated as second-class citizens. Civil-rights legislation ensured equality in education and voting. Other race-based laws were struck down or repealed.
Then came LBJ's "war on poverty". Among other things, that started the modern welfare state. Lyndon himself was quoted as saying "I’ll have those niggers voting Democratic for the next 200 years."
The imposition of welfare altered the playing field. Blacks once had strong families and social structures. Welfare encouraged the worst human traits in it's subjects. Families were destroyed, idleness rewarded with "free" food and housing, morals destroyed by the loss of the atomic family and the work ethic. Too many blacks succumbed to the temptation to sit around and have more babies in order to increase their government checks.
Fifty years later, these people, impoverished spiritually and morally, naturally congregate in the inner cities, unable to earn enough money to move away, incapable of employment in many cases due to the ghetto disdain of education and "acting white".
Gee. Looking at the whole subject from a fresh perspective, I see that "segregation" was cunningly moved from state and local law to the federal level, by the changing of definitions and the inevitable workings of the "war on poverty". Did LBJ and his minions see the final result of their policy?
I think it was premeditated. From the same links above:
“These Negroes, they’re getting pretty uppity these days and that’s a problem for us since they’ve got something now they never had before, the political pull to back up their uppityness. Now we’ve got to do something about this, we’ve got to give them a little something, just enough to quiet them down, not enough to make a difference.”—LBJ
America is more segregated in some areas now after 50 years of affirmative action and enforced desegregation than in the 1930s.
No new federal laws will ever fix this. The solution will be extremely painful - cut off the welfare and force people to survive on their own intelligence and will.
There will be blood. Any way we try to fix the mess will result in violence and death.
There's a real good reason I call them "Demonrats".
