It turns out that those in power around the world have every incentive to keep the gains to themselves and keep their population desperate -- desperate people have to weigh their economic decisions against their physical well-being and continued existence and play the game not to gain power but not to lose everything. And our answer in the US seemed to be that the market is always right; if parity can't be achieved by lifting the poor around the world up to a near-US level of middle class, then it must be reached by pushing the middle class in the US down to desperation level and reducing our overhead to compete on a world stage where other leaders in power can more easily ignore the negative externalities that they push on their population.
It was, in a word, stupid.
It is too easy for the wealthy of the greater world to ignore the problems they create at home by being 'citizens of the world'.
I don't agree with Trump on much but I do agree that relying upon the market to fix all ills hasn't worked. We need to flex the economic muscle we have and tie trade to political reforms or find a way to bypass the powers that be and pull up the people directly. Otherwise, we are stuck in a race to the bottom.
