Now, take away liquidity support and the hunt for yield and there's a problem going forward. You can only generate bubbles of this magnitude if there are assets that are either undervalued, or are at least perceived to be undervalued, and that can serve as fuel for the bubble. US equities had been flat for a generation back in the early 1980s. US housing was cheap and patterns of demand were changing. Commodities used to be a niche market. Finance changed all that, pumping and dumping these asset classes and taking profits along the way for twenty-five years. It was a great run while it lasted, but now, after the bust, could it be over?
