That's a very evolutionist stand, which is proved to do more harm than good to society. There are economic options out of capitalism and communism, for that matter.

If you think that capitalism is going forward or a valid place to start something from, it surprises me that you're even in this community, since even Marx himself abandoned the idea that capitalism was the necessary (although wrong) path to get to socialism.

The progression of humanity was from hunter-gatherer to larger tribes to city-states to eventual feudalism by the late Antiquity all the way up until around 1600. We've not even had any kind of pure capitalism since then, only some hybrids of capital and socialism.
