My youngest son was watching "The Xs" and one of the bad guys, Glowface, was devising a plan to ruin the world's economy. It went like this:
1. Rid the world of non-dairy creamer.
2. Coffee will become undrinkable.
3. Workers will no longer function without coffee.
4. The world's economy will grind to a halt.
Sounds reasonable, there's probably not enough black coffee drinkers out there to keep the economy afloat on their own.
