We still jail people who are financially unable to pay fines. This happened frequently to the indigent population in my town. They would be ticketed for all sorts of nonsense. The jail got so full that the Sheriff just started releasing people.
It's been going on way too long. I think about it every time I see a cop.
It's 10x worse than when I was growing up because municipalities realized no one was keeping track of the amounts of the fees/fines, and they just raised them.
Along with making everything against some law?
I really think the only way to stop it is to tie Fees/fines to income.
