During the boom rental properties were scarce and pricey supporting sales at inflated prices,, bad decision? YES ,, but the blame for the most part goes to the FEDS and Wall Street ,, this was an irresistible avalanche of cash for them while they inflated the bubble.
My parents were children during the Great Depression. That and WWII were the defining events of their lives. While I do not equate the RE bust with the Great Depression or WWII, I suspect that the bust will have similar effects on many who will spend decades getting themselves out of debt. While paying debt they do not buy as many consumer goods and thus are something of a drag on an economy that relies on consumption.
