Generosity and poor

There was a news that a delivery boy of the food outlet, cancelled the order and ate the food just outside the home of the customer. If a customer cancels any order, after the delivery boy picks it up, the delivery boy can have it for himself. The poor delivery boy was probably hungry that he indulged in this deception. Similar incidents have been reported in several cities in India. The boy who delivers food, (within a time frame of 15-20 minutes) often goes hungry. He satisfies the hunger of customers with dedication, but no one cares for his welfare.
God gave clear commandment of the Nation of Israel. His concern for poor is evident. Poor should not be deprived of their food or dignity. Poor need not beg but go and collect their share after harvest. “When you reap the harvest of your land, you shall not reap your field right up to its edge, neither shall you gather the gleanings after your harvest. And you shall not strip your vineyard bare, neither shall you gather the fallen grapes of your vineyard. You shall leave them for the poor and for the sojourner: I am the Lord your God.” (Leviticus 19:9,10)
Ruth as a poor migrant went after the reapers finished their job and collected grains. (Ruth 2:3) Boaz was generous and commanded his reapers: “Let her glean even among the sheaves, and do not reproach her. And also pull out some from the bundles for her and leave it for her to glean, and do not rebuke her.” (Ruth 2:15,16)
Boaz generosity paved way for Ruth to be integrated not only with the Nation of Israel, with his family who become fore-parents of King David and Lord Jesus Christ.
How does modern governments provide for poor? Is there generosity evidenced in the culture of society today? How can Christians and churches be models for such generosity?
Am I generous like Boaz to poor, migrants, widows and other marginalized?
