Right, among other things with the money that others pay back monthly for their loan
No, you misunderstood that:
Example: You pay 3% interest on your loan to the bank. The bank pays 2.5% of that on to the central bank. What remains with the bank? 0.5%. And a lot of other things still have to be paid from that. Whether it is 0.5%, more or less, others here can report better. But do you understand the principle?
I have often asked myself why you can't simply get a loan from the state at 0% (or at least lower) interest,
Why would anyone then want to pay back the loan? That opens the door wide to all forms of fraud. Besides that, prices will rise even further. Such a harebrained idea...
when banks are accused of simply creating their money and enriching themselves on people and then driving them into ruin if something goes wrong)
A bank cannot create money. They sell a service (loan) in exchange for money (interest). Like a physical product or even software. You pay for something, you get something. The conditions are transparently disclosed. Full repayment loans are possible.
Why should a bank play welfare if customers don’t keep their side of the contract? The bank doesn’t drive anyone into ruin. It is the people themselves who do so through divorce or similar things in life. Every adult knows that you have to part with things you can no longer afford, whether jewelry, car, or house. My goodness, grow up,
