I am not any kind of expert on economics; but the current rumblings about sovereign debt sure have me worried. The head of the European Central Bank, after all, has said we are facing perhaps the worst economic crisis the world has ever seen, and it is his job to steady the markets by downplaying the dangers. Britain has begun, like the US, just printing money, and Britain looked more financially secure than the rest of Europe. We seem to be moving almost inexorably to a sovereign default by Greece, which looks increasingly as though it will set up a domino sequence that could cause Italy, Portugal, and Spain to default as well. If that happens, ... almost guaranteed to be a worldwide financial collapse, with huge amounts of wealth wiped away.
