Yeah, I've had a couple of people tell me that prices never go down.. and while it's true that obviously $100 in the 1970s bought way more than $100 does today, prices do go down in the short term as companies compete on price. In the US prices got real, real high in 2008 in the Global Financial Crisis but prices and inflation did go down in 2009.
Even recently, prices for so many things went crazy in March 2020 and inflation was hardcore, and then with the US Fed giving stimulus cheques, both prices and inflation came down in May 2020.
Currently the US CPI inflation is 7.1% compared to 9.1% in June... I'm not sure that I can say I've noticed changes in prices for me... but I'm honestly cutting spending as much as possible because, um, I'm also pensive and a little scared for the short-term future.
