>despite being the biggest country on the planet
Size doesn't matter irl and can actually be a hindrance. Part of why Russia stayed a serfdom state until the 19th century is partly because they had only virtual control over their peripheries. The local Cossack and religious figures were the rulers, by virtue of being the only ones possible locally, which lead to atomized communities with brutal local leaders.
>having the most resources
Gas is cool but isn't anything spectacular. They don't have the same potentials as the Saudis or other arab countries. It's surprisingly one of the few assets that make the russian economy relevant.
>having more people than most of the rest of Europe put together?
Europe is 740 million people ; Russia is 140 million people.
>Only explanation seems cultural to me
The explanation is that they had a very autocratic dynasty that maintained serfdom for very long for a plurality of reasons, which pushed away the average Russian from individualism and very tolerant of their conditions. The cossacks had somewhat of a frontier mindset but these were part of the lower nobility iirc. When the Bolsheviks came to power, it made things worse by centralizing the russian state even more and imposing a totalitarian regimes. As all totalitarian regimes before the advent of mass communication, the USSR was deeply plagued by a local aristocracy of bureaucrats and by inefficiencies which lead itself to delay its full exploitation of its potential. Since then, they've been unable to change because one man has assumed control over the country and switched from a fight against capitalism to a fight against "western degeneracy".
This is somewhat revealing of their conditions in general. Putin doesn't even need to be a totalitarian ruler because the russians are indeed somewhat tolerant of their abuse. As long as some form of essence is given to their state with bare conditions they'll abide with it.
