"Crony Capitalism" is just a term socialists came up with to shit on capitalism. The reality is every society is going to have some amount of corruption and cronyism. But "Crony Capitalism" isn't an actual coherent concepts, it doesn't have 'principles', its just highlighting something negative that happens in countries, including capitalist ones.
Socialists love to add some negative word 'X' to capitalism to highlight that all bad things in the world are connected to capitalism, and if they could finally defeat capitalism, then the world would be perfect. Instead of actually trying to fix 'X' they will tell you that what we really need to change is 'capitalism'. Surveillance Capitalism, Crony Capitalism, Disaster Capitalism and so on.
Trying to fix corruption, to hard, lets just destroy property rights and money instead. Great idea!
