We have to admit, giving them job is the only thing that you will only realistically do. Creating jobs and having poor people hired is quite a win-win situation. They get paid, you get work done. The problem with this if they are lazy. They got poor because they are lazy in the first place.

Providing food for strangers is quite a stretch, let's admit that. Why are you feeding someone else that isn't family with nothing in return? Maybe you can do this once in a while but doing it daily isn't sustainable at all. They will get comfortable with their life and not move a muscle to make money since they know that you're going to provide for them. Same goes with shelter.

For education, a lot of people are actually doing this to high schoolers. They fund their college and in return, they are going to pay back once they got a great job after college. There are also people who can't produce their own child so what they do is help teenagers instead.

Purpose? How can someone starving have a purpose? They can't even think right. They have to fulfill their physiological and shelter needs before this.
