I would invite you to consider the psychological roots of ambition. What, for example, drives anyone to try to possess more "stuff" than what they need? Why would anyone want to control people, or goverments, or societies? What is unique about individuals that are driven to hoard more and more money--far, far beyond what they need for personal sustainance?
What personal need drives ambitious people to elevate wealth over all other aspects in their lives?
You amuse me, Free...you automatically assume that anyone who "is" ambitious" puts wealth over all other aspects in their lives when that seldom is the case. Most ambitious people seek a better life for themselves and their families. Furthermore most philanthropic charity is provided by those very same "ambitious" people that you look down upon for their greed.
If you want to look at psychological conditions then let's examine why it is that some people feel that they deserve to be supported by those who DO work even though they themselves don't?
