Another narrative is that centrally planned economies tend to go under because once you increase market place participation via provision for basic education and industry to the same levels as everwhere else you have to increase the per-capita production and that's something that's very hard to do without the insights that come from actually working as part of the individual industries.

Which is to say that centrally planned economies have a lot of low hanging fruit for countries that aren't very advanced to start off with, when the fixes are still fairly simple, but are crippled in the long term as the complexity/fluidity of the problem goes up.
