When Was America Great?

Donald Trump tells the New York Times:

No if you really look at it, it was the turn of the century, that’s when we were a great, when we were really starting to go robust. But if you look back, it really was, there was a period of time when we were developing at the turn of the century which was a pretty wild time for this country and pretty wild in terms of building that machine, that machine was really based on entrepreneurship etc, etc. And then I would say, yeah, prior to, I would say during the 1940s and the late ‘40s and ‘50s we started getting, we were not pushed around, we were respected by everybody, we had just won a war, we were pretty much doing what we had to do, yeah around that period.
