I think to say that humans must serve a purpose in society based on their ability to make money is dangerously utilitarian. As it stands, I'd guess at least 20% of adults in America (shot in the dark) do not make any money and rely on others for food and shelter. These people are kept out of harm, and their safe mental state keeps other people out of harm. They can offer community service, familial or household care, and plenty of other things that do not profit them any cash. Most importantly, these people are spouses, parents, children, and grandchildren. They offer emotion and humility. I know it seems like I'm doing my best to assert your rudeness or heartlessness, but I'm just trying to raise the point that one's monetary value is not wholly representative of their value in society.
