> Hard times create strong men. Strong men create good times. Good times create weak men. And, weak men create hard times.
Actually it's the opposite.
Strong men create hard times by trying to show to each other how strong they are. Hard times create weak men because during hard times strong men kill each other, thus mostly weak men remain. Weak men create good times because instead of trying to show their strength they just build stuff so that the world is easier for them. In good times people breed and the population returns to the mean with just enough strong men to start the cycle again.
WWII was the last time strong men created hard times. We are overdue for another round and it shows.
