> Capitalism is a great system, but it cannot be narrowed to greed. Capitalism requires working ethics since we are not able to regulate every aspect of life - it is practically impossible.

Whether it's still Capitalism at that point is an interesting question. Some people seem to call any market-based system capitalism. For others the lack of ethics is definitional.

My own view is that we probably ought to stop using the term "capitalism" entirely for the most part, and be more specific about what we mean.
