2) Extreme Couponers
These two groups are related, both based on an irrational fear of the "what-if", only one has a nicer term (stockpile) for its findings. The other usually just gets in trouble or berated. It makes me sick that shows exploit these people that obviously have underlying psychosomatic conditions.
If this is the future, I shudder for it. We've already lost music and literature, what else is there to lose?
