We live today in a world shaped by capitalism. The force of the markets determine our political, social and economic realities. This world which we now take for granted is actually quite new to history. It is only within the last two hundred years that capitalism is the prevalent economic system for most of the world's population. But capitalism did not arise out of nothing. Historian Henry Heller argues in his new book, The Birth of Capitalism: A Twenty-First Century Perspective, that capitalism grew out of feudalism in Europe over a long period of three hundred years through struggles among the various classes that made up that society.
