Exactly. Credit scores are a scam and an incentive into having a credit card and overdrafting.
Instead, there are laws that restrict you from buying or mortgaging at a monthly cost higher than x% of your monthly income
It’s called “level of indebtedness” or “financial burden” and it’s typically 40% of net monthly income. So you cannot get a loan that would put your total monthly installments (counting all of your credits) above 40% of your income.
