The chart you showed, consumer debt to gdp peaked at 300%. So the chart implies that consumer debt is about $45 trillion. The Federal Reserve reports consumer debt at $2.4 trillion at 6/30/2011. Entire loans outstanding for the entire US banking system only total $6.7 trillion.
So who do you believe? Some guy from Australia who says US consumer debt peaked at $45 Trillion or the Federal Reserve System who says it's 5% of that amount? My money is on the Fed. Apparently, you place great faith in the aussie.
Regarding Japan, the nikkei 225 had a p/e close to 100 in 1990 when their market tanked. Our p/e has averaged around 15 or so. Currently, it's around 12 times earnings.
Look I don't mean to be overly critical but come on now, Inlet, you need to be able to differentiate reality from baloney.
