Well its about money and quality of life for those who are professionals and those who depend on it for their livlihood, but there is a place for hobby pilots also if you are mainly interested in fun, self improvement, and instruction. I would never hold a part-time flying job if it robbed a full time pilot of their opportunity, and I would never pay to fly commercially. These are no no's. But you can find lots of things to do in aviation just the same and I would not discourage someone from trying it as a serious hobby.
