I wasn't talking about businesses, I was speaking in general about the properties of large systems. The Roman Empire got too big to govern, and putting Karl Marx OR Ayn Rand in charge wouldn't have helped. This conversation has nothing to do with ideology. But, since you insist on bringing it up...

Big systems, like rain forests or coral reefs or planetary climates, do not have a purpose. They just are, and they evolve. They are natural phenomena. We can harvest their resources, nurture them or abuse them, destroy them, perhaps even manage them to our long-term benefit, depending on how well we understand them.

Human governments and economies are human artifacts. They have a purpose, and that purpose is to serve human needs. When that purpose is no longer served humans have the right and obligation to change them. And humans also have the right to decide just what that purpose should be, and what those needs are.

It is inevitable that those who benefit the most from any economic or political system will disagree violently about purpose and need with those who benefit the least. Those who do well resist change, those who do not will seek it. There are always exceptions, particularly from those who feel either secure, or victimized, a few scattered individuals like us who are operating on some abstract level of ideology, but as a rule, political and economic conflict is not about intellectual or philosophical differences. It's about class struggle. When the mob is hungry, it riots. When Pharaoh doesn't want to open the granaries, he calls out the chariots.
