Yeah. Like why can I get a draft beer anywhere in Amsterdam for 3 euros MAX 4. At the top of the 5 star Okura hotel, beers are 4/5 euro. Of course, fancy beers can be 6 euros.
But in the USA, it is not uncommon to see Budlight selling for 8 dollars or more. (don't forget to tip!)
Yes I noticed the same thing, but only in the cities. Cost of living there is generally higher and income is as well. If you go to a small town in the US a beer can be 3 dollars and a coffee 1.50 or so.
If they weren't using the same currency there would probably be difference in inflation due to very different economics between let's say New York and some tiny rural village.
