Manufacturing is a dirty, dangerous, manual business. I think the small guys will tell you that environmental regulations killed manufacturing in the west, not labour costs. We've been living in lala land with it all offshore, out of sight. If US/EU-level environmental regulations got applied and enforced globally, we'd be sent back to the stone age. Not to mention the litigation risks, intellectual property risks, trade union cartels, needing to hire an electrician to change a lightbulb, etc. (All added up, it's hopelessly calcified, but whatever...)
Don't get me wrong - I really care about the environment - but most regs here are just to look good, not actually about stuff that matters. And pushing it into the third world, where they don't protect the environment at all, is counterproductive.
