True Tito, it isn't just about Unions. It is sbout companies wanting cheaper labour. Thus America boomed post WW2, but when the chance to put people in sweat shops for pennies came along companies grabbed at it because 'Hey globalisation, we will be a service based economy'. Thus the jobs were shipped away to Japan, Korea, China, now Vietnam and India and on it goes. And what happens in those countries? They eventually lose their jobs to somewhere cheaper too.

Here is a bit like the UK at the dawn of Thatcher. They will likely open the borders to poor people willing to work for little to fill the cracks, but eventually you are left with a hollow shell that once was. That is America, that will be here, and on it goes as globalization rules.
