In light of the fact that there are poor people in the world, what is the meaning of "You satisfy the will of every living creature"? HaShem provides enough sustenance in every location for every person, even though the wealth is not equally distributed. He gives prosperity to the rich in order to grant them the merit of showing kindness to those who are less fortunate.
Lesson: When man acts compassionately towards his fellow, the resources of the world suffice to provide for the entire community.
App: Emulate HaShem by sharing your wealth others, if you have the means to do so. If your present financial situation is challenging, trust in HaShem's mercy and compassion.
