As much as I wish it would all dissappear tomorrow, I'm a little skeptical that it's going to be as fast as we would all hope. A buddy the other day was talking about Guatemala, and how they're economy is way more fucked than ours has ever been, but they still have all the trappings of civilization. they haven't gone back to uncivilized ways of living. Neither has Somalia, which barely has a government to keep people in line. I think that one big thing that has to happen before any real change can happen is that the population HAS to come down. All these billions of people will fight to the death to keep civ alive, even if their stocks are worthless.
So, in summary, as much as the economy is fucked, I don't think we can talk about collapses on particular days, this week has proven it. it's going to be a long arduous, agonizing collapse. If you haven't, learn to fight, there are some fucking psychos living in the wooded places I want to live in, and they have more guns than most people i know.
