>From what I'm seeing around me, people usually grab small short term advantages over other people even if they suffer long term consequences together

I would argue this is a symptom of capitalism, not an inherent property of human nature. We live in a system that requires us to compete to sell our labour in order to survive. This leads us to think of everything in terms of competition.

This is why so many people in creative jobs (including software development) end up feeling like they can't do their work efficiently because their manager won't let them. Because the employer-employee relationship is based on exchange, it is fundamentally antagonistic.
