To me, there's a difference between something you need to live that was made poisonous by the government requireing aid and former managers pulling pensions of $200k+ a year. If I lived in Michigan, I'd have a big problem bailing out the FDNY pension fund when I heard that. It's endemic too, look up "LIRR Disability abuse".
I am fine with bailouts as long as systems are being put in place to avoid repeating it in the future. That's for Flint, pensions or banks. Obviously the prevention step never happens....
Neighboring towns near Flint took care of the problem at their own expense. Is it fair to them that Flint doesn't have to pay? Perhaps we should pay those neighboring town back, with interest, for the work that they did? Aren't we encouraging irresponsible behavior if we pay for Flint but not the other towns?
"Representation" is a bit of a vague concept in US governance.
