All valid points. But let's remember that America today is not the America of the Reagan era. We've become so dependent on cheap products coming from abroad, I doubt we will be able to adapt if the rug was pulled from under our feet. Also the whole mentality has changed with the emergence of the Internet. Now the entire globe is connected and to implement an isolationist trade policy would almost be suicidal. Finally, it's worth remembering that our economy is a consumer economy. In order to sustain a economic growth, consumer spending needs to be sustained. Bringing manufacturing back home creates a two-fold problem. First, it will raise the cost of output across the board. This will dampen consumer spending. Second, if we choke off foreign investments, namely not importing, it will effectively kill the world economy, which in turn, will have a negative consequence for our own economy.
