Free trade is about identifying and exploiting the potential energy of the system, in the process the imbalance is reduced and profits are made
What a clever metaphor. Is it supposed to mean something, or is it just a pathetic way to make your argument seem more scientific? To anybody who is dumb enough to buy it, it also has the propaganda effect of making it seem as inevitable as entropy, when in reality it's just the opposite - a matter of policies conceived by politically powerful people.
Why?
You are also totally ignoring the gains in the 3rd world
Another myth comforting to free traders. There is no reason that China, for example, can't grow on the basis of internal consumption, just as the US did. I also find it an astounding coincidence that policies which are supposed to benefit the 3rd world, just happen to do so in a way that benefits the already rich in the developed world. There are other approaches, but I assure you that one which doesn't enrich the wealthy will never be enacted.
