I’m not saying that was good either, but middle European countries started with a similar situation and got much farther. I recognise the USSR as a lesser evil than tsarist Russia, but that doesn’t mean it’s good. More like an upgrade from 2/10 to 4/10 while other countries went paths that lead to 8/10
What about not enslaving people?
And of course people in weaker economies get paid less, they also need less since everything is cheaper.
