The lowest common denominator of a group without a shared vision is money. Money doesn't have the emotional content of a real motivator. Money is a satisfier, not a motivator. When you don't have it, it's all you can think about. But when you have it, you don't really think about it.
Motivation decreases as appetite for money is satisfied.
A motivator is a passion that increases when satisfied. For example, I am motivated to learn about what makes teams work. The more I learn, the more I want to know. Money isn't a shared vision. You are fooling yourself if you think it is.
