Earlier quoted context omitted.
Inflation ending means stable prices. A general reduction in the price level (aka deflation) comes with horrific unemployment for some people and income loss for everyone else. If you think you want that, you don't.
People are complaining prices are too high, not that it's going up too fast.
You could just declare all nominal prices 100x lower and make everyone rewrite their loan contracts, it'd make the penny useful again too, but the best approach is to just wait until expectations reset or voters find a new thing to get mad about.
(Prices can go down in some sectors, like food/oil/technology; nobody really has a good explanation for when this is safe and when it isn't.)
Also, in this case the guy who got elected was running on explicitly inflationary policy - low interest rates, tax cuts and tariffs. Though I don't think voters knew that.
