>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.

The system is run by employees of whatever agency handles taxes. Neither the employees nor the agency keep a portion of the taxes. If they do not have the money or will to fix it, people are supposed to pressure their representatives to give them the money and mandate.

If this truly came down to an intent to squeeze more money out of people than they owed, that would almost always come from the law's wording. Again, pressure the representatives.

The only times an agency would squeeze money is when it's funded in large part by fines or fees, or if an employee is committing fraud and pocketing some of the money.
