All this raises the question of what “capitalism” is to begin with, a question on which there is no consensus at all. The word was originally invented by socialists, who saw capitalism as that system whereby those who own capital command the labor of those who do not. Proponents, in contrast, tend to see capitalism as the freedom of the marketplace, which allows those with potentially marketable visions to pull resources together to bring those visions into being. Just about everyone agrees, however, that capitalism is a system that demands constant, endless growth.
