Is it a problem?
We are not capable pf producing many goods at a cost competitive on the world market.But we do make lots of those things others lack the ability and brains to do.
We do it well. Until two years age we were beyond full employment and required immigrants, many illegal to function.
One purpose of the current recession is to deprive the illegals of their jobs.
NAFTA is not the problem in spite of the isolationist bitching.
NAFTA is working as good as the EU....what a success story there /sarc
