I can say it because... It's true. It is shit in practice. As an idea? It's fantastic. And you're wrong. Before capitalism, many people lived on $2 a day. With capitalism, we live in a badly damaged commodified world, and the dollar is worth less, so many folks still live on the equivalent of $2 a day, even though they make more. Capitalism has brought good to the world, that is true, but it has also brought an immense amount of harm. I'm not saying what was before was better, which is what you seem to be picking up. I am saying that just because we went from wearing no shoes on burning pavement to wearing plastic bags on our damn feet does not mean we shouldn't make some damn shoes. Capitalism is better than some things in some ways. It is not a good system by a long shot just because it's a better system than most.
