The quote just summerizes the concept that has been going around since probably the dawn of time ... at least modern times anyway.
It's a dumb concept that's obviously wrong. (Fascists love it, though.) There isn't even a decent
correlation between "strong men" and "good times," much less
causation... and without that part, none of the rest of the meme is worth thinking about. "Good times create weak men"... OK, so what? Should we avoid good times, then?
It also doesn't make any sense when applied to the real world. When were the "hard times" that created the great orange emperor? When were the "good times" that created Soft Joe, or our previous weak Muslim president? Was Dubya the strong man that created good times, or the weak man that created hard times? None of it makes any sense.
The only purpose that idea serves is try to convince people that they need to elevate strongmen (literally:
strong men!) in order to bring about Good Times. It's fascist propaganda, plain and simple.
