Manufacturing in a modern economy such as the US is something doomed. Not because we cant make it well, but because workers cost so damn much! Yep, would you still be all "our jobs" if your cost 2x as much? Yep, that also means less money for other things.
Let me leave you with something:
Would you be sorry for the Whale Oilers if this was 1890-1910 and essentially every one of them lost their jobs? There is no more whale oil, the whole industry had become obsolete because of the energy-denser crude, and killing whales to power anything sounds like a shitty deal to me. Yet, them losing their jobs had a negligible impact on the 100 years of extremely rapid development as a result of that industry tech switch.
Industries die, jobs become obsolete, and thats just the nature of technologic advance. The sooner it sinks into the populous, the sooner we can start looking into more important things than the Tea Party and actually make some headway.
