But given how many of the investors in the UK actually study humanities at Oxford I'm not sure what you're trying to accomplish there. Unless you really believe that studying humanities somehow makes you a more moral human being that then doesn't go on to destroy the world, which clearly isn't the case.
And for reference Boris Johnson studied classics at Oxford, fucked a dead pig as part of a fraternity initiation ceremony and is now doing his best to dismantle public healthcare in the UK. So I don't think the "make our society better" statement holds any value.
EDIT: comment below is right, it was David Cameron, not Boris Johnson. And he studied Philosophy, Politics and Economics. So while the last paragraph is half correct and half mixed in with Boris Johnsons history, both of them have been working hard on selling off the NHS. Boris also hasn't started as many wars. So, I guess Boris is better on a relative scale?
