Deflation is a bad thing. It also doesn't necessarily mean things get more affordable for people.
It's a serious issue and is not good for the country or the people in the country.
In fact it's usual that the central banks main goal is to stop deflation. That's why central banks are usually separated from government policy also. Deflation is such a huge concern the central bank can overrule the wishes of the government and put in measures that will lead to a recession. Deflation is worse than recessions.
Economics is a lot more complicated than all the memes on this website of. Capitalism bad, communism good.
