An example of "worth" (as in net worth) which has potential to simply evaporate. Individually disastrous for families assuming intergenerational wealth was safe in the parents house, fiscally disastrous because the economy will be in shrinkage as it was in the sub prime, because of excess housing stocks causing a decline in construction spend, and declining values forcing more people into drawdown on capital, or a retreat from spending. Under employment hits. Deflation isn't fun.
