My anecdote is about prices in a single country skyrocketing, I think you only find that particular country’s data less interesting because it’s a country you’re familiar with.
I do have more international data points for you, though.
All the American fast food joints keep their prices pretty consistent across countries I’ve been to in any year, within ten percent or so of conversion rates anyway.
As for local fare in Taiwan, inflation is blowing up here. prices in general here seem about 50% higher than 5 years ago.
China’s prices have all doubled since ten years ago, except for housing, which is slightly cheaper(evergrande). Not that they were ever expensive.
