| It's important to remind everyone that this common adage is very wrong, looking at history (at least as long as we take "strong men" to mean "powerful armies"). Tough times mean brittle impoverished societies with weak armies that crumble easily. Easy times (prosperous, politically stable societies) are what creates strong armies. War requires huge investments of resources, so only prosperous societies can have powerful armies. War also requires strong leadership that can't be corrupted or divided - only politically stable societies can ensure their war leaders will not turn cloak or start fighting among themselves. |
Rather, hard times (economic depression, warfare, disease, etc.) creating strong men meant creating toughness, resilience, patience and conservatism in society. The endurance of these events would eventually (somehow) allow the next generation to have its progress and luxuries; peace, economic prosperity, education. But easy times create comfort, arrogance, impatience, over-leverage; spoiled people don't know how good they have it, and so they think it'll last forever. It gets taken away from them, and they fight amongst each other about whose fault it is that everything is slipping away (blame immigrants, blame opposing parties, blame foreign powers, general polarization and divisiveness; them vs us).
Everything goes to shit, and the cycle is renewed.
