Why would they ever fix the system. Some number of people will just pay it and those people are pure profit. Heck, fixing the system costs money.

It's the same evil math behind every other billing scam that sails under the flag of ignorance.

Speaking of ignorance, to all those people saying you forgot to fill out a form, there are several states that are known to be maliciously sloppy about this sort of thing. You file a form and they silently reject it or billing you anyway on some questionable pretext because they can. NY is one of them. Doesn't surprise me that IL is too since both states are kinda cash strapped.
