Capitalism is just an algorithm. It's only an ideology if you make it one. It's just a system of allocation and ownership that has clear tendencies and side-effects, well understood for many decades.

The experiment has shown that, as the system evolves, it doesn't have a stable state. One needs to bolt on additional controls to try to keep it in a stable state, or else one gets concentration of wealth and power. All the symptoms of that are pretty obvious with endless spilled ink. I really don't think this stuff should be controversial to people who are normally thinking about the behavior of complex systems.
