First of all, let’s try to avoid American-bashing, and stay respectful to everyone.
I’ll start: for me it’s the tipping culture. Especially nowadays, with the recent post on !mildlyinfuriating@lemmy.world with the 40% tip, it just seems so weird to me to have to pay extra just so that menu prices can stay low.
The expectation of everyone having a credit card as soon as they can get one and paying everything with credit to somehow “build” credit. Sounds such a great way to get people into financial trouble at a young age.
In Germany the system is shit too. There is a private monopol company that calculates and stores a score for you. The calculation method is secret, but we know several things can lower your score, such a having too much bank accounts/credit cards, moving too often, if you ever had debts and how fast you paid them and so on. When you ask a bank for a loan, they check this score and may decline if it’s too low. There are some people who have problems getting a loan because they have no records for their score.
