If one is overly reductionist about homo economicus, that it’s all about the money, then this is true. Entrepreneurship, like other “jobs,” offers non-pecuniary benefits, and I think that weighs heavily for self-selected entrepreneurs: degrees of freedom not found in traditional jobs, the immense satisfaction of turning your own ideas into reality, a fire-hose of decisions you have to make without approval from a chain of command… I’m sure there are others.

However, this underscores your point – can this be taught?
