Truth is we've become soft. In fact, one way or another, we probably won't be around to find out. Folks lived without all kinds of stuff for a long time. Given enough pressure it's pretty radical what small groups of people can do. Always remember, the United States was born because less than 10% of the people decided they had had enough. As for finding those people, well that's a few steps ahead, right now everyone needs to start picking their hill.
