Very weird that I am so old and have literally never heard this mentioned in a TV show or book or movie or anything.
In four out of five states, if you go to prison, you are literally paying for the time you spend there.
As you can guess, this results in crippling debt as soon as you're released.
The county gets back a fraction of what they hold over your head the rest of your life until you commit suicide(or die naturally and peacefully with the sword of damocles hanging over your head).

Unfortunately the government has been very busy snatching up essential liberties and writing bullshit laws, and it's almost impossible to keep up with the protests and lawsuits. The politicians get paid to be there, and can spend all of their time on legislation. Once they pass something, boom, it's in effect. Then it costs organizations and citizens tons of time and money to protest and appeal what was so easily done by the legislators.
