Another month, another rationality quotes thread. The rules are:
- Please post all quotes separately, so that they can be upvoted or downvoted separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
- Do not quote yourself.
- Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson. If you'd like to revive an old quote from one of those sources, please do so here.
- No more than 5 quotes per person per monthly thread, please.
- Provide sufficient information (URL, title, date, page number, etc.) to enable a reader to find the place where you read the quote, or its original source if available. Do not quote with only a name.
A poor person comes to the bank and wants a loan. The bank judges them a high risk, and either declines to offer the loan or offers it at a high rate of interest.
No way of drawing up loan contracts differently can affect that basic relationship between the risk of a loan and its cost.
Banks are not charities. They provide a service in return for a profit. As with any business, they must make a profit on whatever service they provide, at least on average, or they will cease providing that service. Even if the bank were set up as a non-profit organisation for the good of its customers rather than its shareholders, it still has to have a business model that breaks even. Selling £10 for £5 is not a business model. Laws and regulations that make a business sell £10 for £5 result in the business ceasing, or changing its form to avoid the laws.
ETA:
I think the causality works the other way round. You can't make up social rules and say "wouldn't it be nice if people behaved like this?" That's not to say that what we have at present is the only possibility, but one has to think about how an alternative would actually work, and not merely imagine happy faces.
FFS the bank makes a profit in every example provided. I don't want to say that you obviously didn't read the post, but I honestly can't see any way you would come to post this comment otherwise.
Loans are a service. Loans with gentle defaults are a more desirable service. Those seeking loans would often purchase such services preferentially and at a profitable premium to the bank, if they were available or if asking for them were socially acceptable. Laws should be passed to encourage banks make such offers.
