So what did Unions, OSHA, Workmens Comp and the EPA accomplish in the long run?
They made the U.S. a horrible place to engage in any business that could easily be outsourced to another country with a lower regulatory burden, taxes and wages. The worker's paradise angle worked until the economy globalized, now it doesn't.
So increasingly there are no low skilled jobs in the U.S. Automation is also a union and job killer because its better to spend a lot of money on a machine than deal with employees. Wage rates are dropping, the U.S. runs massive trade deficits and government is massively in the red because its spending more than its shrinking tax base will support (tax cuts for the rich under Bush certainly helped, as did over promising on Social Security, Medicare and Medicaid, and squandering on the defense-intelligence complex.
Wonder why healthy unions in the U.S. tend to only be fire, police, teaching, government, truck driving. Because those are the jobs that can't be outsourced.
There was a sweet spot in there, maybe around 1950 where unions and government regulation hit a sweet spot, they'd wiped out all the massive abuses of workers earlier in the century and built a big middle class, and then they over rotated and made the U.S. a horrible place to do business. If you don't have business you tend to not have jobs, then you have a lot of people living on food stamps and Medicaid.
