Crime is primarily driven by poverty and other inequities when social supports are lost or dismantled. For the most part people turn to crime when they don't have other options available.
There both tends to be a delay while the effects take hold and while pay for the general population is stagnant while prices rise, there hasn't been a corresponding rise in long term poverty.
It is complicated, but things like the ACA reduced a lot of medical debt stress and low unemployment are working in the other direction from increased inequity. The states that decriminlized or even legalized weed had corresponding drops in crime as well.
Side note: Some cities have had spikes in crime, because it is never a perfectly even change everywhere.
