To illustrate why I ask, consider this set of questions: How's your house price doing? Where would your 401K be, if central banks withdrew life support for banks? How steep is a college education this year (hint: on average, 10-15% more than last year)? How are weekly grocery and gas prices doing? Where are commodity prices — not to mention gold — headed? Bubble, bubble, toil, and trouble: these days, it seems, everywhere you look, there's a bubble inflating — or popping.
