But if people stop buying crap won't the crap making and marketing companies stop hiring so many of these college grads and instead of buying iphones they can't afford they now have to buy food they can't afford?
You have to right? Because if you don't borrow money to pay yourself to do useless stuff, well then you can't afford to eat... At least this way you're buying some time to figure out a way to get someone else to borrow money and pay you.
