Lots of well-connected people have become unimaginably wealthy off that. And in every case -- there are zero exceptions I believe, there are huge bribes/kickbacks paid.
"Totalitarian" China has a population of 1.4 billion. They have about 2 million people in prison. That is less than 2/10 of one percent.
"Freedom-loving" USA has a population of about 340 million. We have 1.9 million people incarcerated (not counting the millions they want to put in these new concentration camps. That is over half a percent. In other words, we incarcerate THREE TIMES as many people per capita as China does.
The median cost to the taxpayers per US prisoner is about $65,000 per year. That means taxpayers are giving about $125 BILLION to these prison systems, most of =which are now private, for-profit corporations. And that is not counting the billions more we are giving to the profiteers who are building these concentration camps. It is big money. That's what Trump likes.
But Bannon and Miller like the cruelty of it. There is something for everyone to like in this system, unless you are inside the cage.
