When we were highly unionized in the US we had a much higher standard of living than we do now.
Not exactly. Union laborers made above market wages at the expense of non-union labor. It was production that raised everybody's standard of living, not unions.
We got along just fine with GM Ford and Chrysler and somehow I don't feel particularly enriched by being able to buy Toyota Nissan Kia etc.
GM, Ford's and Chrysler's labor costs are so high, they lose money on every car. Even if they destroy themselves, the unions won't take cutbacks.
Now to get bact to your original thought if that is what you want to call it manufacturing left the US because of greed on those at the top.
Bad management and unions are a lethal combination.
The only people that benefited from mfg leaving the US were the politicians, bankers and business owners.
Politicians and bankers yes. I don't see what other choice businessmen had. It was either offshore or go out of business.
If China can only succeed by exporting their crap that should tell you something is terribly terribly wrong.
If it was crap, consumers wouldn't be buying and WalMart wouldn't be selling.
Americans are in for a huge drop in their standard of living until there is some kind of balance with the rest of the world. Any attempt to wall us off will only make matters worse.
