See, that's the funny thing about fiat currency that isnt tied to anything that is valuable - you can't. You have to make more if you want to increase your spending power. Not only more, but more plus whatever the real inflation rate is to keep your original spending power the same. This is by design. IF YOU WANT TO INCREASE YOUR PURCHSAING POWER YOU HAVE TO BE COMPENSATED MORE BY WORKING HARDER OR FINDING A JOB THAT HAS A HIGHER MARKET VALUE.
Deflation may give a very temporary increase in purchasing power, but with an economy as debt laden as we currently have the defaults and bank runs/holidays will remove any savings from the economy in short order as there isn't enough money in this fractional reserve system to satisfy all of the debt and promissory notes that have been created. Deflation is a true shit show. Once this occurs, output decreases, people become unemployed, foreclosures for businesses, farms and homes occur and people wind up homeless. Output decreases because people have no money. Will the dollar go farther? Yup, but no one has any to speak of.
All those paper assets - 401K, stocks, retirement funds during deflation? Worthless. It is surprising how little deflation it would take for this to occur: right now we have approx 20% in real inflation; during the Great Depression deflation ran at 7% annually and that was a killer. Hopefully the 2% inflation number the Fed keeps trying to get to makes sense - its kind of the Goldilocks area between too much inflation and "oh shit", AKA deflation.
