FWIW there's also YC's Zidisha in the microlending market which cuts out the middleman (but still charges interest)
For example, I heard about 3d printer group with rule: we give you 3d printer printed parts for free, but, when you will assemble your own printer, you must print 2 kits and donate them to others. From consumer perspective, it's 100% of interest, but from 3d printer hobbyst perspective, it's not a problem at all, because they will have printer, which will print them parts. Business is like a printer for money.
Positive outcome is not guaranteed, of course, but fear of loss, as shown by some losers, drives majority to success.
I know you're speaking pretty abstractly, but let me run with it for a bit to illustrate the case for basic income:
Better yet, is give money and let the person decide whether to buy a fishing rod or a fish. Which one is better depends on a lot of uncertain and hard to observe (for an outsider) factors like:
* how badly an immediate fish is needed
* how viable is it for the person to learn to fish?
* how useful a fishing rod would be given the environment (people close to a river that has lots of fish probably have more use for a fishing rod)
* what the opportunity cost of a person's time is (if they have another good alternative job then they would logically prefer the fish as supplementary income rather than a fishing rod which must replace their old job)
Loans are shifting my perspective: if I will eat that fish today, how I will return that fish? I will not event think about that when I have a food for free.
Give fishing rod, not a fish.
