1990? Oh I remember it. In Brazil they wouldn’t be listing the year though, but the month - hyperinflation was raging on, back then. (I remember the 100 cruzeiro coins. They were cute.)
Anyway. The number doesn’t match any pair of prices:
from '90 to '22 (32y): 224%
from '22 to '23 (1y): 162%
from '90 to '23 (33y): 364%
And one detail that they didn’t mention is that +100%~200% between the 90s and the 20s is not a big deal, but +60% in a single year is a big fucking deal. That smells artificial as fuck, reinforcing what people have been saying here about not being inflation but price gouging.
