Capitalism has its perks, great advancements have been made in technology, quality of life and the development of cities that would otherwise have never existed.

The real issue lies when you look at the system in a more holistic, long term view, lets say another 200 years. In that time-frame the self propelling cycle of capital will make the accumulation of all wealth lie in a very small group.

In itself it is not a bad thing as long as advancements are still being made and the average quality of life is improved, however it leaves the system with a very centralized point of control.

This point of control could quickly deviate the system for purposes not entirely in the best interest of the species, put it as "Power tends to corrupt, and absolute power corrupts absolutely." It may be a possibility but not the great peril. The real issue lies in the central group having accumulated all resources, and then not being able to maintain said resources and leaving the whole system open to a single point of failure by a revolt of some sorts. (starting from scratch can take more energy that the energy required to topple the system, and sometimes there may not enough energy to build over...)

Do we really want to have a society were the integrity of it depends on a single point? Maybe we do, but it just might not end up being the most resilient system.
