By fining the crap out of these people and putting them on the treadmill of poverty we intentionally economically marginalize them so they with near certainty can't amass the wealth or power needed to threaten the system. Sure, you could go all in on a life of crime, become a drug kingpin, whatever, but in doing so you've also given the state an easy button to come after you if you get uppity. It's intentional. The system does not want these people to go on to be wealthy and powerful decades later. The absolute last thing the system wants is one of these guys going on to run some regional business empire or whatever and going all in on some political candidate that's gonna screw the jailer's union or apply more transparency to the courts or whatever so the system intentionally saddles them with this debt burden when they're rebuilding their lives.
