Starts at decade born 40's and goes from there. This is the moral equivalent of starting in mid March to look at stock gains. If we had the same information from the founding of our country until today it would probably look closer to a U with "born in the 40's" being pretty damn close to the top of that U. This should not be used by anyone to make any conclusions.

The world just went through massive war that destroyed nearly all of Europes infrastructure and the demand to fix it mostly manifested as opportunity for Americans. Since then Europe has rebuilt and both India and China have arrived on the scene as powerhouses of their own. We will never have the same opportunities that we had then again, or at least we should all pray we don't.
