The facts do not support these assetions, CS. The lower end of the housing market, for example, is the only one seeing any serious buying activity due to the housing tax credit and increased affordability. Also, jumbo mortgages are (relatively) expensive and credit standards remain high with few "alternative" financing options. Higher end home sales are thus virtually moribund. Furthermore, grocery stores, Wal-Mart and other "low cost" options are among the heatlhier retail segments.
The velocity of the money supply has contracted sharply since the recession began. Consumers are not spending as much while unemployment has risen substantially. The main reason deflation has not come about is the massive goverment spending that has replaced some of the lost consumer demand. Also helping are extraordinarily low interest rates as determined by the Fed, currently at 0.25% (essentially zero). Both of these have helped us avoid, thus far, the kind of meltdown that was experienced during the 30's, when the govt was not so inclined toward intervention/Keynesian deficit spending. Chariman Bernanke has studied the depression era his whole life and is determined he will not make the same "mistakes".
That said, the long term affects of such policies are still unknown and, some have argued, will ultimately prove to be worse than if we had just let nature take its course.
Here is a quote from on of my favorite commentators:
"Reality is staring back in the mirror at the American consumer, and especially the Boomer generation. The psyche of the American consumer has been permanently seared. We are watching savings beginning to rise and consumer spending patterns change for the first time in generations. Even as the authorities try to prod consumers back into old habits, they are not responding. Borrowing and credit are actually falling. Banks, for whatever reason, now want borrowers to actually be able to pay them back. Go figure.
Frugality is the new normal. We are resetting the underpinnings of a consumer-driven society to a new level. It will require a major overhaul of our economy. The normal drivers of growth - consumer spending, business investment, and exports - are all weak, and it is only because of massive government spending that the second quarter was not as bad as the two previous quarters and that the coming quarter will be positive."
