Thats not entirely true. That doesnt mean capitalism is a exceptionally horrendous system. Unlike "faux communists", many Marxists, and those who have been influenced by Marxism, actually sing praises of capitalism. And in fact it is Karl Marx himself who has said some good things about capitalism, and he believed it was a necessary step from older more ancient societies before they could move on to communism. "Capitalism" has been great for expanding the economy and even lifting the masses into a nicer place than they were before, and its a far better system than many others, particularly many of those that have come before in world history, but its still a problematic system, and one that has mass inequality, and one that is also very unstable.
