By profit we usually mean financial gain, but it's more general meaning is just a gain or a benefit. If financial gain is a motivator, wouldn't it make sense to harness it to things that 'profit', that is benefit humanity, rather than seeing financial gain as unconditionally good, ecept for the restraints we have put on it (illegal drugs, for example)?
The obvious example of where we've got it wrong is harnessing it to work - human labour. With one habd we're trying to be mor efficient - achieve more with less human labour, but with the other we lock work to income. Makes no sense.
Another example. Would it not make sense to incentivise people remaining healthy, or being restored to health from illness? How does this fit in with people making money from pharmaceuticals? You're ill? Good - I'l sell more drugs, employ more doctors and nurses, build more hospitals.
I don't know if money can be used to incentivise only those things which are truly socially desirable, but if it isn't, what are we doing with it.
