1. Germans were retarded, their supply lines and frontlines were stretched thin, the main reason Barbarossa was so successful at first, was simply a combination of luck and Russian incompetence in the early stages of he invasion.
2. the Soviet Union over the course of the war became the second most industrially powerful nation, they could easily outproduce the Germans and shit out a ton of cheap but extremely effective designs such as the T-32. Not to mention the sheer amount of resources Russia had at its disposal
3. After Stalin stopped being a retard and let actually talented commanders lead, not just the ones that sucked his dick 24/7, things turned for the better. Soviets were capable of using a steady stream of equipment, manpower, and tactical genius to win key battles.
So as any sane /his/torian would tell you, the Germans never really stood a chance against the rapidly industrializing USSR. In my opinion, the reason Russia sucks major ass today is most likely the fact they are still just sending conscripts to die in Ukraine, not using their airforce almost at all, and using weapons designed to fight a whole different type of war.
