I agree with this (though not some of the earlier things, e.g. that Greece is less indebted than the Netherlands). Two observations: 1. If they started buying their own debt back en-masse the price would probably go up (as with any other good where demand increases). 2. The problem of Greece, and other poor countries, is that they have trouble mustering resources. Raising 18% of GDP from a poor population isn't that easy. If Greece was a wealthy country they probably wouldn't have the debt they have.
