One weird thing you missed is the “length of credit” though. Let’s say you get your first credit card somewhere as a kid, and now you’re 40 and haven’t had anything else. Suddenly, that bank wants you to pay a monthly fee to keep your account open. If you get a new credit card somewhere else, and cancel your kid-card, your score is going to get hit quite a bit, no?
If you did it “correct”, you’d have 10+ different cards lying in a drawer at home to tons of different credit agencies.
It’s all an insane game that you have to play, despite the fact that it can usually be played “for free”.











You’ve got the right idea for the European system though. “Tourist tax”. It’s usually low enough that it’s not a big deal, but I was shocked when I checked in at a hotel in Greece and the receptionist wanted 5€/night from me.
