Cool, thanks for the stats. But that still doesn't address what I mentioned about the threat of unionization itself being a deterrent to potential manufacturers (for example, the recent debacle between Boeing vs. the NLRB).
Also, what about the other two factors I pointed out about incredibly high tax and regulatory burden US manufacturers are saddled with?
Do you honestly believe lowering the corp tax rate to say zero would have even slowed down the off shoring?
