I'm afraid you got it all completely wrong. Most prices (except high tech gadgets) are typically very rigid downward and mild, non-destructive inflation encourages putting money to use from passive cash to active capital form. Deflation on the other hand encourages being passive, holding on to cash, not investing, not taking loans and is as such quite devastating to any economy. Japan is a typical example where deflation alone has crippled a very healthy economic growth for decades.
