"Can't we do something about this?"
In order to do something, you have to see it as a problem. Many, if not most of the people here at FR see this as a good thing. They're business owners and they want labor as low as it can possibly be in cost.
The FR line is that Americans should retrain, or open their own business. For those incapable of starting a business, or the 50 some year old who is losing his job to India... sucks to be you.
And even though capitalism is good, and free trade is fundamentally the best option, this causes people to run to the left, the socialists. Free trade is good, but when it's unrestricted on one side, (ours), then it's not so good.
There are many here who believe that the US should be a totally service/information based economy, manufacturing little or nothing. That was tried in Spain. Didn't work out so well for them.
It must be like Communism to the left. The only reason it hasn't worked is because the right people haven't tried it yet.
