The problem with that question is that capitalism is an ideal, where the word is generally taken to mean "perfect competition," and even if we satisfied our current expectations for a capitalist society, we would still have the ideal and fall short of it. And another problem is that a "country" as a political entity is inherently socialist. True capitalism would mean everyone is able to defend their property while no borders exist and no threat of violence is tolerated anywhere. Such could exist in a geographic country, but never in a political country. Its an ideal. This, by the way, is why I think religion is required for capitalism.
