Economists are horrible people, study says
Because it belongs to a douchebag.
But before all you econ majors get your demand curves in a twist, hear what the good professor has to say.
Citing research by Cornell professor Robert Frank, Grant makes the compelling case that economists are neither generous, nor cooperative. And that's because they've swallowed one of Adam Smith's main tenets: people act out of rational self-interest.
Emphasis here on the self.
In short: economists don't feel bad about acting in their self-interest because — well — the economic theories tell them that they should be selfish.
