If we stopped outsourcing as many jobs, then more people in the US would have jobs, which means we would produce more wealth right here in the USA.
Now maybe that would cause a few percent inflation, but like it or not, the Federal Reserve has determined that a few percent of inflation is stimulative to our economy and they strive to achieve such. So if we had a few percent of inflation due to cost push pressure, it would simply help to achieve the Feds goal, without the fed having to intervene by pumping more money into the system - so most likely there would be no additional inflation than what would have occurred without more jobs.
In the mean time, our wages would naturally tend to rise as employers have to compete harder and harder for workers, consumption increases as more people get jobs, production increases as businesses strive to meet demand, and the GDP increases. None of that is a bad thing, it's basically what happens when we have a strong economy.
You think that a strong economy = crash?
