The intellectual core of the human race came together here during and after WW II. That core's descendants are still here, although who knows for how long. Asians have gotten rich copying American technology, but they have been unable to produce any breakthroughs on their own. A good example of this is the clown show that was China's missle program until Bill Clinton sold our guidance technology to them for campaign cash for the '96 election.
True, and true.
(we can be thankful to Clinton for soooo many things, can't we?)
