BigZoMan it doesn't matter who you know or what you can predict, a person you never though of you did something for might some point save your life, maybe they don't maybe it someone else you know. The point is some policies and ideas are better than others, and WIIFM, isn't one of them that is good in general.
See this
Its penicillin, and your philosophy if unchecked, that place you had lunch the other day at that spot run by your homie who also subscribed to WIIFM when he decided to cook whatever it was to cut cost to serve your sandwich, you now have dysentery, and it's a mutated strand that's stronger than normal.
You live in dumbfuckestan, so nobody has health insurance anymore because WIIFM, you feel like you are going to die, and all the money you have to your name is $1000, and unless you pay 1200$ for those pills you are likely going to be in a lot of pain shitting yourself all over the place, possibly die or both, what are you going to do?
And there is no layaway plan, so Good luck!
