Whether or not unions CAN be good is irrelevant.
They simply are NOT needed in America 2004.
Governmental agencies and laws protect the workers from the abuse and dangerous work conditions of the past. A federal minimum wage prevents slave labor, and beyond that, good ol' fashined capitalism should dictate the wage for each job.
The very first thing most union employees learn is that they themselves are worthless (and worth less) without the union. They look at their pre-dues paycheck and rejoice in the higher wages.
It's as if they couldn't earn it on their own.
The economic prosperity of this country relies on supply and demand. When a union "forces" an inflated pay scale it skews everything towards an unrealistic target.
Many jobs have been lost BECAUSE of the unions.
Because of their often unjust wages.
because of their myopic job functionality.
Because of their inbred complacency.
It's not the only problem facing Americas workforce, but it's certainly a big one.
It's sad when the best, most positive thing that can be said of something is that it was important 100 years ago.
