If you take an economics or a political science course, you're taught that humans are supposed to be rational wealth accumulators, each acting as an individual to maximize his own wealth in the market.
This is the world we live in, a world of safety and happiness and order, a world without love. A world where children crack their heads on stone fireplaces and nearly gnaw off their tongues and the parents are concerned. Not heartbroken, frantic, desperate. Concerned, as they are when you fail mathematics, as they are when they are late to pay their taxes.
