Now I'm being humorous there but there might be some social engineering needed. And I wonder if one could promise a share of any future profit (if there is any) which comes from the use of the grain.
I always knew 'reward' vs 'punishment' motivations always exist. But only today I had a blinding flash of obviousness that 'no-reward' 'no-punishments' scenarios are equally demotivating.
And understandably so, I would not put in extra hours at office if not rewarded, yet I'm not getting punished either.
zero sum game
One month i only sold 5, but you asked for the other five. If i give you, there will be more things in circulation and now i will be offered less money for my things. Maybe only next month, but i still lose.
now, you give your exceeding production for free. That person that got it for free makes grain alcohol, sells it cheaper than your paying customer. next month your paying customer will either also want it free, or at a much lower price to remain competitive, lowering your next month profit.
The whole problem is people trying to make more money with the grain by creating false scarcity. if they sold way cheaper when they had more production, the original paying customer would have bought twice the grain and made twice the grain alcohol to begin with. and none of that would have been a problem.
How do we make recycling and efficiency more important than personal gain?
The challenge comes when the choice is 'put to use, but only if its free' or 'rots away and nobody gets anything.' People choose to have it rot. Its the prisoner's dilemma writ large, and one of the inherent traits in humans, and one that religions seem to try to overcome.
