The problem is that they tend to benefit their members in a zero sum way. For example the LIRR wants a double digit raise not in exchange for hitting targets on on-time arrivals or some other metric. They want it or they strike and hold the community hostage. It bothers me that there's no value exchange it's just take take take, and ultimately at my expense.

Worse, public sector unions are ultimately at my expense in a way that I can't even fix by not buying the product, since they're taking it from my taxes.
