But I note here: the main thing is the expensive frame, financed for that, instead of paying cash and focusing on price-performance... yeah yeah, that's how the economy thrives
The problem with this attitude you describe is that the economy only keeps thriving sustainably (not just a flash in the pan) if old debts are replaced by new ones. For example, if the Americans suddenly raised their private savings rate to the German level (aka everyone pays off their loans, fewer take out new ones), their domestic market would collapse. It is therefore also much less frowned upon to grant people credit there who would not get it under a different financial culture.
One can now debate what makes people happier. After the financial crisis, I somehow find the answer to that quite easy.

Regarding 0% financing again:
The bank earns most on a fully repaid loan. There’s no getting around that. But where other models simply state an interest rate, here they babble about 0% (pure marketing speak), while often fees/insurance are charged, just under different names. In the end, it’s just a loan the bank profits from. And what the bank earns, you have less available yourself.
I lived in my first apartment for 10 months with a camping stove and cardboard boxes in the kitchen until I could buy my first kitchen outright.
Almost zero understanding among acquaintances: EVERYONE would have financed the kitchen at 0%. So you also have to swim against the tide if you want to act financially smart today. Where do we actually learn how to handle money?
