If you could rid the world of money...?

Money provides motivation. why should someone study for years to become a doctor, lawyer or teacher or other profession if he can make as much pushing a broom. Rewards are a motivation however unfair the situation may be. A person would need to know what kind of stem would be in place to replace the one we have before abandoning it and have an idea if it would be workable and what to do if it didn't work.
