The real root issue, is that we drastically underfund rehabilitation.

There are generally just not enough rehab spots, therapists, psychiatrists, etc. to address the unmet need. There are not enough of them in the health system because we don't pay for them enough.

There are also not really resources in the prison system either. A lot of the prison-reform movement was actually supported initially by conservatives, because low-tax governments cannot afford to lock large numbers of people up for petty crime.

No matter what the solution is, it requires spending money.
