@realjohnboy,
yes, it is a change in the last 30 years of hyper consumption. You not only have the continuation of the 30 year trend of living wage jobs disappearing, but now you have households tapped out on credit, their wealth reserve (401k and home) has shrink and you have the government needing to raise taxes substantially. Recent history is of the class warfare struggle being won by the rich, so unless this changes the government will be balancing its books on the backs of the middle class and working poor. Discretionary income will continue to shrink rapidly.
We still have a lot of wealth to disappear, because homes at the upper end will not regain their value. The McMansions are too big, too far away from jobs, and unlike the mansions that were cut up during the last depression these are not suitable for reuse as apartments. We have McMansions going at auction for 1/3 of the stated value. This loss of wealth has yet to be accounted for on the banks books. The current owners are in a holding pattern, they pay their mortgage in the hope that they will at some point get out of their property by selling, and not even trying to sell now because they know the market is frozen.
Americans will be making due with less consumption. We have been pigs for a long time so this is not a huge problem, except for those segments of the economy that were dependent upon hyper consumption. We are starting to see them go away, but this reshaping of the landscape has only just begun.
