I think your take on it is correct in the minds of so many Americans.
It's amazing that the predominate race in this country can't seem to put two and two together [or want to live in denial of facts] that Black people are only about 12% of the population, and when they run out of Black people to be the "product" of the Prison Industrial Complex Industry Plantations, they are not going to just walk away from all those millions/billions in profits. White people in America can keep thinking that the militarization of Police is America isreally only for Black people if they want to.
Most of the Jews in Germany initially agreed with the rhetoric and twisted philosophy of certain people/groups/races being 'inferior', until they found out that they, too, were to be included in the groups/people/races deemed 'inferior'; by then it was too late.
The idea that prisons should be privatized for profit is sick and a conflict of interest in that the prison industrial complex are going to make sure they have a constant flow of inmates to fill their prisons in order to make profits from federal, state, city, town, tax revenues. Lawyers and Judges profits from high incarceration too. This is why there is such a high resistance to legalizing Cannabis on any level. You notice the steam is being taken out of the movement, I doubt anymore states will do what Colorado and Washington did making Cannabis a legal recreation drug and citizens are free to grow 6 plants without breaking the law. They will allow medical on a very limited basis but hell no they don't want laws that remove convictions of any kind.
