Left-wing economics is idealistic, and the basic assumption is that everyone is a good guy, and he will work in the best interests of the system.
On the other hand, the basic assumption behind right-wing economics is that everyone is inherently a bad guy, and will work only for his own benefit. Hence, systems have to be devised so as to align a person’s selfish interests with the system’s interests.
To put it in other words, left-wing stuff is ideal. It assumes best case performance, or marginally below best case performance, from all players in the system. Similarly, in assuming that everyone has only a selfish motive, right-wing economics does what can be called a worst-case design.
Training in Computer Science inherently teaches you to think about the worst-case possibilities in everything.
In this context, isn’t it? surprising that so many people from a computer science background are leftist?
