People commit more crimes when they have less opportunity. People have less opportunity when they grow up in high crime neighbourhoods. This is a negative feedback loop which was started by slavery and accelerated by segregation and redlining.
It’s not enough to use a hands-off approach. To correct the problem requires an active push in the opposite direction, to restore opportunity and break the cycles.
Edit: Think of it this way. You and some friends are playing Monopoly, drinking a few beers and having a great time. An hour and a half into the game (we all know games of Monopoly can last 4 hours or more), you discover one of your friends has been cheating. Now what?
He says "Sorry everyone! I'll stop cheating now and everything will be fine."
Is that true? Of course not. The proceeds from cheating may have been used to acquire the orange properties and maybe even put houses up on them. Every time you and the other friends land on those properties you end up paying rent to the previously cheating friend. Rent that he should not be collecting because those assets were acquired by cheating.
This is what it's like to have historical injustices continue to perpetuate into the future.
