Except protectionism makes everyone poorer in the medium term and actually causes international conflict. Who do you think gets drafted to fight war when trade wars turn to real wars? Perhaps if society used the increased wealth to benefit everyone the value of global interconnected trade could be felt by everyone. This is an easy fix, return to the post World War Two tax policy that built the middle class. Return to a well respected government that drives large scale work like highways, scientific research, the space program. Think about how much technology is a direct result of military research (GPS, the Internet, rocketry, etc) imagine if we mobilized on the same scale for exploring space, basic research and innovation and entrepreneurial activity.
