Anyone that has had to deal with labor unions get a real education in how to "screw the man". It sort of resembles how the National Education Association operates. Keep all of those dunderhead teachers on school payrolls, watch the education of kids get flushed down the drain. That thinking operates in the same way many unions deal with other sectors of our economy. Protect the very people that are sinking various industries like the domestic auto companies.
The difference with public sector unions is that it's impossible to kill the host organism.
