I've watching WEF interviews with with some of the most credible economists in in the world. These folks maintain their credibility as the have "no ax to grind" or no alterior motive to their opinions. The economic conscientious, of the economists, is that the US government is: "weak leadership", "populist directives", "inability to act", "misdirected", "short sighted", "ineffective" e.g. These valuations are obvious due to congress's (recently displayed) inability cut military/security spending, alleviate earmark spending, rejection of the US Debt Commission's plan, inability to instill voluntary austerity, escalation in annual budget, continued corporate welfare e.g. So the question is WHEN (I don't believe it is any longer a case on "if") the US starts to have trouble selling it bonds, will YOU step up and help by "buying stock in America". This was the strategy during during WWII and Japan's current debt crisis and it's going to happen again.
