Much of Europe will lose more money proportionally than the U.S. will by the time this downturn is finished.
Can't say for the developing world. The expansion of the domestic markets is real in many places. I've been traveling and meeting with many Chinese business men from industrial hydraulics, oil rigs, subway infrastructure, cement technology, etc. Times are good for these guys and the banks still have the ability to get them loans. How long it will last I'm not sure. This current business environment extends all over the country.
Most of the U.S.'s real financial issues don't involve countrywide financial IMO, it's more along the line of no education in personal finance and all the things that stem from that; inadequate retirement, credit card overuse, heavy debt, low savings, and absurdly poor political choices like allowing SS and medicare to get where they are.
