And because of WW2 America accelerated out of the Great Depression and into an even larger and more dominant global economic superpower - an economic superpower that fueled the middle class and all the working blue collar jobs that Trump voters pine for.
The US has about the same share of global GDP today as it did in 1910-1920, before the US emerged onto the global stage. Your premise is wrong. The US was more powerful economically before WW2, than it is today. The particularly robust and brief post WW2 bubble was just that, courtesy of the rest of the developed world being blown up. In about ten years the US will approach $30 trillion in national debt, a sum so great nobody even seriously talks about attempting to pay it off any longer, and interest rates can no longer rise above perhaps 2% or 3% because the US Government would go bankrupt.
We're talking about 1980, not 2016. I didn't say they're the same relative economic superpower today than they were decades ago.
If I wanted to be facetious (this is obviously ridiculous), I would say that the solution to your complaint that America's economy is in decline is to start another war.
