Disagree. What we had, have, and are in danger of losing, is a cultural heritage that encourages effort, responsibility, and cooperation. IOW, a civil society, which we got from English ancestors.
If you look at Africa, you'll see discord along tribal lines, and absolutely no history of a civil society. Mugabe runs his country as sub-Saharan Africans have always run their countries.
I fear that our own society is losing its civilized roots, and that we will have a lot of big cities looking a lot like Mugabe's Zimbabwe. It may become, if not the norm, at least very common.
