Yeah it is pointless to try to convince everybody. However, among my close friends and relatives pretty much everyone sees the same thing as I do and several friends have also sold recently or are in the process of getting out.
Anyone who is too ignorant or to stupid to see this thing coming deserves to get punished, I have no sympathy for them. It is survival of the fittest. Anyone who has been living here in SD has enjoyed a much better life than most people of the world so what ever suffering this crash causes them will pale in comparison to the difficulty many in the world suffer every day.
