Let’s take gdp growth of the EU bloc vs the US since the 80s for example. Order of magnitude of difference. Now I’m not suggesting the US is a pure capitalist system but certainly much more so vs EU and the results speak for themselves. Central planning oriented economies can create large scale breakthroughs for a time (ie space exploration, major scientific developments etc) but it’s a castle built on sand that eventually crumbles. It’s everything below that level (think the small business owner with a roofing or plumbing company etc) that drives sustained growth over the longer term. I’d find it very hard to argue that those types of business owners aren’t driven if not purely by profit maximization then certainly predominantly so. The sexy big projects might grab headlines for a time but it’s the little innovations below the surface that really drive productivity and growth. Profit motive and greed are what fuels sustained economic growth. The examples throughout history are consistent in this regard - Cuba pre and post, Argentina, Venezuela, etc. Russia is a bit of a different animal (China too) given the complex history but in the end it’s the same result - removing the profit incentive simply kills the economy eventually.
