If Greece was to finally capitulate to the markets and declare bankruptcy, how different is that to the 2001 Argentina default? It seems crazy to me that banks are allowed to deal with corrupt inept politicians who accept debts that are not repayable on the behalf of a country's people. Countries should be allowed to declare themselves bankrupt and after should follow a period of distrust not unlike personal bankruptcy. As a result banks would think twice before lending to poor debtors. Or is this a completely niavie viewpoint? I'm not in any way an economist so I'm genuinely interested to hear people's thoughts
