I'm not even sure that compound interest is entirely bad. I just think that its ubiquity is wrong.
Like, why do student loans have compound interest? I thought the point of higher education is that all of society profits from it, not just a select few?
Why does medical debt have compound interest? Why is someone being punished annually while paying off a debt they did not anticipate or seek out? More pointedly, why should someone expect to profit exponentially from that situation?
