Socialism in the extreme is a hazard to stable government. But so is capitalism, federalism, militarism, and any other -ism.
They should look to Chile. A can do country. One which almost went socialist but avoided it and came out doing pretty well for itself.
The problem with those counties is that the whether they go communist or socialist or any dictatorship is that the caudilo mentality permeates everything. Same behavior in the Caucasus region. Mexico has been ravaged by this mentality --their economy was pretty much on par with European countries outside the big five in the early 1900s --but caudiloes happened.
I find it strange how people view socialism in black and white, but not capitalism.
Give me an example of “real” capitalism.
I’d say the Scandinavian model is a pretty happy middle ground.
(Sidenote: State capitalism and market socialism are essentially the same thing)
