Our two biggest American heretofore weaknesses vis a vis The EU and China, will turn into our greatest strengths going forward...
For decades now, our economy has spent considerably more as a percentage of GDP on defense, than those two have. That defense spending is like money in our bank - that we can draw down and shift to more productive pursuits. The EU and China don't have that "money in the bank" to draw on and to compound their issues, as we reduce our wasteful defense spending, they'll be caused to increase theirs.
Similar is true, in the context of exports. For at least several decades now, our economy has been considerably less dependent upon exports, than theirs have. We've tended to consider that to be one of our economy's weaknesses, and it probably was. But now...our economy has considerably more upside than theirs do, in terms of our expanding exports. And, it looks as if we're starting to take advantage of it. Their economies on the other hand - being as dependent as they are on exports - essentially have little place to go but down.
