> people are not being locked up just because they are black, or poor

I just said this elsewhere, but I knew many people in college who used illegal drugs, and none of them were ever locked up (or even searched). When we have a set of laws and we choose to enforce them on some communities but not on others, then we are in fact locking people up just because they are black or poor.

Others have already pointed out that high incarceration and felony rates (in part due to the drug war) have contributed a whole lot to the social patterns that you mention here. I'll agree with you on one thing, though: our social programs today are in a particularly ineffective state with some messed-up incentive structures and still not enough resources to actually solve the problem. I'd much prefer something like a universal basic income to the complicated, market distorting system we have today. (But I still think that getting rid of these programs would be far worse than what we have now, even if the incentive structure would be more straightforward.)
