I agree with those points, especially competition is an important one. It has been the furnace of our progress too, so this is a double edged sword.

I think people will not stop forming a social hierarchy, and so competition remains a sticky trait I think.

True, the idea that you can do better than the Jones through hard work is alluring. Having a job is now a requirement for being worthy, the kind of job defines your social position. Compare with the days of nobility though, where those nobleman had everything but a job ("what is a weekend?").
