Excellent post 4plex–it kind of scares me that I could be RAS’s myself on the bubble and crash (one or two seconds maybe).
Another point I have noticed; that if enough people believe a fact as being true, like the earth being flat, then it IS flat. “Group Think” offers a peace of mind somewhat like a religious experience. To argue against the group makes you “one of them,” (everyone knows who the “them” is except me).
I can remember hearing in the ’60’s “Your home will be the worst investment you’ll ever make, but a necessary one.”
