How exactly did you get to the conclusion that fascism needs "strong men"? The current US regime has nothing but the weakest, most fearful men clutching to power. You really think that Trump's call to execute senator Kelly comes from a position of strength? Your current bad times came from a few decades of weak men letting their fear and hatred (and greed) guide their vote -- strong men had very little to do with it.

Anyway, the quoted saying is not about any specific ideology, that's just your own projection. Here's the cycle reformulated without any specific ideology:

Hard times create strong men: hardship breeds discipline

Strong men create good times: discipline breeds prosperity

Good times create weak men: prosperity breeds complacency

weak men create hard times: complacency leads to hardship
