I think very much like Ampfixer...well... millions do.
IMO, a change is taking place, not the end. Western countries are going to lose a lot in the relatively near future. Simply, for decades already, we have been spending more than we earn, because we don't need to pay the "full price" for anything, but the debt is simmering in Asia.
Our standard of living should not be as high as it is.
IMO, It depends very much on how fast the standard of living in China and, say, India, will rise. If it keeps skyrocketing, the production costs will rise so fast that in ten-twenty years or so it will be profitable to have some industry in the western countries as well.
This all is just result of free capitalism, which the "preppers", AFAIK, very much support.
Asia's rise will cease when western countries can't buy their products anymore, and then things get gradually balanced.
Had there been different versions of protectionism, custom fees etc. the way it used to be, this had not been possible so quickly and in such a massive form. It's made possible by the miniscule group of very influential and wealthy people/companies who make more money in China than keeping westerners employed.
We in the rich countries are now used to consume things that are made in Asian cost environment. When we have to go back to consuming based on costs that actually give bread to the ones who do the work in Europe and North America, we'll have to accept a radical decrease of living standards. But before that comes unemployment and hard times. How hard it gets, depends much on the social security systems, because the violence of the riots is very much dependent on how desperate people are.
I believe that the "real", sustainable standard of living in the industrialized world would be something like in the poorer countries of Europe. Only one car in the family, you eat meat only 2-3 times a week max, you don't travel by air routineously, you don't buy clothes, or anything, just because you feel like it etc. I do know most spaniards, greeks, portuguese, polish etc. would consider that kind of life luxury now. Paying nearly 10$ a gallon for gas is tough when you earn 800$ or less in a full time job, if you get paid...
