The US is sinking ... sinking ... sinking, page-54

There is a lot of chat on here in regards levels of government debt & all is ok as governments can run deficits as long as they service the interest & GDP keeps pace. Here lies the problem. GDP isn't keeping pace. The only other time as far as I'm aware that US debt to GDP ratio was this high was WWII Last I looked the world wasn't at war! A Fed spokesman just overnight said they would be pleased if they could raise rates in mid 2015. Watch out interest costs they are an out to double, triple or far worse.
Comments like governments can run with reasonable amounts of debt in perpetuity, which is correct. The issue is that debt levels in the likes of Japan particularly but also the US to a lesser extent are unreasonable & getting worse by the day.
