All true. However, it's a curious quirk that both Hitler and Stalin were paranoid psychopaths. Yet, Russia managed it's resources to produce relatively low tech T-34s and single engine attack/fighter aircraft, while Germany fritted away it's industrial advantage.
I wonder why the difference.
Access to resources, and having Allies with the means to ship you high quality machine tools and all kinds of other goodies while concentrating your production on other things is the difference. After the end of 1942 and early 1943, around May, the Germans had lost, and many of them knew it. The rest of the war Germany was on the defensive and the Allies were basically just mopping up. Losing many men in pointless offensives like Stalingrad and Kursk means you have to start stripping your country of men needed to operate factories, etc.
The soviets even managed to grow their economy at a higher gdp than did the US in the early post-war. We dismissed this as they were very good at producing steel and concrete and building dams, but when it came to innovation, we were better. I'm not sure that's an adequate explanation.
That was impressive, but again it wasn't possible for them to do that entirely on their own, and the quality of their production wasn't very high. If it weren't for Allied aid, they would still been at the Vistula in 1945, and nowhere near Germany, even with the German defeats at Stalingrad and Kursk. They could never have launched offensives, much less large ones.
