Why is deflation considered a bad thing?

Your ysis is pretty good. Deflation can result in greater value for your dollar. However, if you have debt like most people do and in particular a mortgage, you have to pay off inflated values with a deflated dollar. This is why so many people are walking away from there homes because the value of the home is inflated while the market has now gone down. Why stay in a house that cost you $500,000 and now is worth $200,000? This is why deflation can and has caused our economy so many problems right now. Our government by the way is at fault for this tragic event but I don't have the time or space to explain that here and now. Research Freddie Mac and Fannie May along with Barney Frank (Dem. Congressman from Ma.). You can also blame Alan Greenspan and his easy money policy when he ran the FRB.
