I am not even sure if countries other than ex-communist use this specific model.

Ah, well, that's a rather important detail.

I'm not saying that your model is entirely wrong -- just that it's not universally applicable. By the way, another place where you are likely to find it is in Central and South America. However I think it's way too crude to be applied to the West. The interaction between money and power is more... nuanced there and recently the state power seem to be ascending.
