It's pretty cheeky, random internet guy, to tell multiple central banks--whose function can be placed squarely in the realm of economics--that they are wrong about what inflation is.
And that would even include something like "As a poor, single mother working 2 jobs in Pennsylvania, how is my life better under the current administration?"
That would be my response, based on the past actions of republicans under Trump.
I believe your argument, though, is that those in power can redefine existing words to whatever best suits their current needs and we should all accept that and not consider why we had the original definition in the first place?
