Deflation really only has a bad name because the definition of inflation was effectively changes in the 80s. We used to consider inflation to be the expansion of the money supply, deflation being the opposite. For whatever reason the word inflation was repurposed to describe and increase in *prices*. That metric is effectively useless though as prices are just a side effect of multiple factors including the total money supply, supply and demand of a particular good, technological innovations, etc. Deflation as we see it today was actually a common thing historically. Prices for a good decrease in time as we become more efficient at producing it and as demand decreases when something better comes out.

> Deflation really only has a bad name because the definition of inflation was effectively changes in the 80s. I wasn't alive at the time, but the modern definition makes a lot of sense to me: Monetary base is one of several factors impacting inflation, so conflating inflation and (an increase of) the monetary base seems quite confusing. > Prices for a good decrease in time as we become more efficient at producing it and as demand decreases when something better comes out. It's totally fine if some prices go down, but the more useful notion here is that of purchasing power. When people expect the purchasing power of a currency to increase meaningfully, they start deferring purchases and investments (since most/all goods and services are expected to be cheaper tomorrow than they are today), which can cause inefficiencies just like inflation can.
