"Wall of debt" could hurt the fragile economic recovery

U.S. and European governments are expected to sell about $4 trillion in bonds this year, creating a "wall of debt" that could course through the global financial
system for years. One concern is whether the market and the fragile economy could absorb the debt or whether the situation would result in a Greek-style crisis for less creditworthy governments. Analysts differ on their assessment of the issue.
