People have been divided into rich and poor. And it is the obligation of the rich to share with the poor.
If G-d wants the poor to be provided for, why did he create a society that was unequal to begin with? Why not provide the poor person with his needs directly, and not require him to undergo the indignity of begging from the rich?

Our sages answer that G-d created the world in a manner that allowed people to perfect it. Not that G-d 'needs' any assistance from us, He could have created the world in any form He desired, including one that would not have needed any human intervention. But he wanted to leave room for our input, for our effort. When a Jew carries out his Divinely mission in this world, He becomes a partner with G-d and receives an abundance of blessing, not as a gift but as a reward.
All the blessings that G-d grants to us - health, children, livelihood - become a deserved grant rather than a donation.

G-d wants to allow us the opportunity to learn kindness, compassion and benevolence, to emulate His ways. And so we observe a lack in someone else and we try to fill it.

The affluent one must constantly recognize that it was not his power, creativity or intelligence that brought him wealth, but G-d's blessing alone. And when we share what we have with others, we call G-d's blessing upon ourselves and are then able to give even more to charity.

When Moshiach comes, please G-d very soon, we will see how our many acts of charity and loving-kindness throughout the generations, has transformed this world into a more perfect one and our mission, of becoming partners with G-d in creation, will be complete
