Socialism is inherently crony. It is a system which is highly centralized and as such encourages the consolidation and then dissemination of wealth (such as it is) and power to vested interests, sometimes quazi-private, (as is the case with Petrobras) often within the government. This is the sad legacy of modern Venezuela and Brazil. (And pretty much all socialist systems.) That these two countries are now failing so spectacularly is to be expected. This is what crony systems do.
