I had. But the theory of that book is criticized and probably wrong. Culture is important, yes, but the capitalism culture is not related to the anglo-saxon or protestant culture specifically. It is related to any culture which benefit of a large freedom.Capitalism isnt a cultural phenomenon, culture is important to it emerging or remaining, or havent you heard of the Weber's The Protestant Ethic and The Spirit of Capitalism
That's the facts: capitalism spring up in every environment where private property of means of production is allowed.The idea about capitalism spontaneously springing up is ahistorical BS which not even any of the major capitalists theorists are too keen on. I'm sure the tea party will get the memo eventually.
