" Europeans had highly developed regional and national cultures and societies before they bolted on Protestantism. America, on the other hand, was half-created by Protestant extremists to be a Protestant society. American academics accept the idea of American exceptionalism in one of its meanings—that our peculiar founding circumstances shaped us. “The position of the Americans,” Tocqueville wrote in Democracy in America, “is…quite exceptional,” by which he meant the Puritanism, the commercialism, the freedom of religion, the individualism, “a thousand special causes.” The professoriate rejects exceptionalism in today’s right-wing sense, that the United States is superior to all other nations, with a God-given mission. And they also resist the third meaning, the idea that a law of human behavior doesn’t apply here—scholars of religion insist that explanations of religious behavior must be universal. The latest scholarly consensus about America’s exceptional religiosity is an economic theory. Because all forms of religion are products in a marketplace, they say, our exceptional free marketism has produced more supply and therefore generated more demand. Along with universal human needs for physical sustenance and security, there’s also such a need for existential explanations, for why and how the world came to be. Sellers of religion emerge offering explanations. From the start, religions tended to be state monopolies—as they were in the colonies, the Puritans in Massachusetts and the Church of England in the South. After that original American duopoly was dismantled and the government prohibited official churches, religious entrepreneurs rushed into the market, Methodists and Baptists and Mormons and all the others. European countries, meanwhile, kept their state-subsidized religions, Protestant or Catholic—and so in an economic sense those churches became lazy monopolies.*10 In America, according to the market theorists, each religion competes with all the others to acquire and keep customers. Americans, presented with all this fantastic choice, can’t resist buying. We’re so religious for the same reason we’re so fat. "
