the most problematic one is goverment employee 工会. The private

company empolyee 工会, if they ask too much, the company just say, Ok we bankrupt, everything wiped out, existing pension decided by court, typically cut a lot. So the 工会 has to give in. For goverment empolyee 工会, the emploer is goverment, to get the vote, they will match 工会's asking price, the consequence, Dem gets elected, by all state citizens pay higher and higher tax to fill the hole. Soon or later, people wil say enough iss enough. Wisconsin is an example, 工会 made the recall but failed.
