alt Hacker NewsOwing money you don't have has disadvantages even without interest.
For example, if you make 5000 dollars a month and get a 5000 dollar BNPL loan for a stereo, payment due in a month, then even without interest, you now either starve or default on the loan (or incur penalties, i.e. the interest you thought didn't apply).
You realize almost every phone in the US that you buy through the major carriers has worked like this for decades?
