a low and constant inflation rate ensures that the economy grows. people think that deflation is good because you can buy more things, but like min wage, people forget that economics is a balance and their gain comes at a cost, in this case either a stagnant or decreasing wage rate (no increments) or unemployment because businesses go bust (especially retail companies, you know, companies that need to hold inventories of goods that are becoming cheaper). dont even talk about what happens if you hae a loan lol.
someone mentioned ow japan 'enjoyed' deflation. its less enjoyable when you consider that during the ''lost decades" since the 90s, unemployment went from 2% to 6% and gdp went the other way from 6% to 2% (and you got to remember that gdp growth in the 60s for japan reached like 12%)
