It was just the statement that "human society has always been able to solve it's problems" followed by a condemnation of capitalism. So I assumed there was some prior system that worked better for solving problems.
I guess they say Mussolini made the trains run on time. And Egypt's slave economy was stable for thousands of years.
It's like I said, I can't see a prior example that is not meaner and uglier than capitalism, or at least as mean and ugly.
Capitalistic Socialism may indeed be a better path for the future. But I didn't think it could be the original poster's intent.
