Russia did though, before the revolution Russia was still mostly agrarian and way less developed then western europe. Under communism they developed faster then any other country up to that point and nearly caught up to the west.

People often compare the soviets to western europe and say they're poor, but Russia was half a century behind the west before the revolution, and the revolution/ civil war caused even more destruction. A better comparison would be a country like Mexico which also was mostly agrarian and just finished a revolution in 1920. Compared to that the Soviet union did pretty well living standards wise.

Just look at there war performance , WWI Russia lost to Germany whose main focus was on the western front, WWII Russia was able to halt Germanies full force after they had conquered France and drive them back.
