The Soviets lifted an unprecedented number of people out of poverty. This was unequalled until China in the following century. They would likely have achieved more and lasted longer without the constant harassment of capitalist countries. (Remember when the US even invaded Soviet soil? Most Americans do not.)
The US and some European powers managed to convince Soviets to switch to an American-style economy, run by oligarchs. Those countries proceeded to loot the Soviet Union for anything they could find. And so we have today.
