The tough times, strong men quote is just a historical fact. I don't know if it's really a Russian proverb as Ivan claims, but I do know that it's true. There were even scientific experiments conducted on social animals that gave evidence to this proverb.
As for the decay of life outside of Russia's largest cities, life is quite decadent outside of European cities in general. The S**t you can see in some countries' countryside is just depressing. And this is not to defend Russia's S**t. Russia needs to get its S**t together, of course, as everyone else should. But using Russia's countryside as some kind of arguing point, whilst disregarding historical/geographic/geopolitical contexts, is just a fallacy that was transformed into a propaganda weapon. Not buying it. And frankly cringe whenever it's brought up in a discussion.
