G1 vs. G7 vs. G20?

We already know that at least some people in major European countries (Peer Steinbrueck, this means you) are mad at the U.S. for “causing” the global financial crisis. But while many of the rest of the G7 are at least complicit – European banks were buying large piles of the same mortgage-backed securities that set of the crisis in the U.S. – many of the world’s less-developed countries may be even madder at the U.S. Henry Paulson has called a meeting of the G-20, which includes some of the larger economies outside the G-7, for this weekend. The hope is that it will help dampen strife between rich and less rich countries, all of whom are being affected by the crisis.
