It's all a huge problem. The average public worker makes almost double the average private sector worker for the same job. That's fraud from the union/democrat criminal pact. I have a big problem with that when we are $15T in debt. And, yes, legacy costs will kill off the USA. The more the average joe blow private sector guy who plays by the rules understands this shit, I hope the more is done to throw out the dirtbags behind it all.
+1 Let's not forget also that (1) non-profits are forbidden under federal law from engaging in political activity, yet non-profit unions are the most blatant political activists and power brokers in the country, and (2) unions are exempt from antitrust laws. These two circumstances alone give unions, particularly public sector ones, unparalleled political leverage. Witness how many times the SEIU chief has visited the Obama white house to influence policy.
