Over 90% of incarcerated people are not in private prisons. They’re a problem for sure, but it isn’t every or even most prisons that are private. The problems with incarceration in the US can’t simply be blamed on private greed, they are primarily an outgrowth and continuation of slavery perpetuated by state governments and the federal government.
I agree, but the primary beneficiary of modern incarceration is the state, not private interests.
