Are they? Russia, for example, is neo-feudalist, not capitalist.
That aside, modern Russia has tons of capitalists... Crony capitalism is still capitalism, and there are tons of proper companies there besides. Not everything is owned by some government-friendly mafioso. But when a regime collapses, like USSR did and there's a power vacuum that's what usually evolves for a while...
They are the least protected class, who live under constant threat of business extortion by corrupt government clerks. That's pretty much the opposite of "cut-throat capitalism".
Not exactly, they are the ones who are friendly with the corrupt government clerks. It's not like government trumps capitalism, it's more like capitalists own friends in high places...
So same as in most countries...
