One thing that I've read before is that switching from a 20 mpg car to a 34 mpg makes no difference to how much one spends on gas. People just change their driving habits to drive more with more MPG.
I bought gas today for $2.60 here in Missouri Ozarks. Nice! I am hearing it could go to $2.10 at the low. That would be a real nice xmas present for consumers, workers, drivers and the stock market.
It seems gas prices have a lot to do with a lot of what goes on.
We could be looking at a period of significant deflation which could ultimately be bad as people put off purchases to wait for price decreases. Could we really see 2% home loans and easy credit next year to stimulate the economy and stimulate inflation? I think we could. Deflation is the ultimate killer of economies.
