If there isn't a bigger reward I wouldn't want to take bigger risk.

In this case, instead of rewards being measured by money, it will be measured by prestige in the community.

Instead of using greed to motivate people i would rather use shame.
Right now greed tells starving kids in africa to get jobs.
Id rather say shame on the workers for failing at their job to feed the world.

Do we agree that what we have isnt working for all of us?
