Sad thing is it turns upstanding, law abiding citizens into criminals. Governments must pay their employees (unions) and if the choice is putting you out of business or themselves - doesn't take a rocket scientist to know who will get the short end of the deal.
You make $50 in three years and Philly says you owe them $300. No, doesn't make sense, but it doesn't have to. You comply or go to jail. That's the power we have given them and now that times are really tough they are using it. Won't be the last story you hear of outrageous injustice against citizens. Next one may be you!
