This doesn't mean it has to be good, just that you convince people to pay you, which is IMHO "easy" with the high software developer demand right now and difficulty for non-devs to distinguish between high and low quality software.
I think though, that as you are saying, open source shines with generic libraries where there's competition and selection of the best, while proprietary software shines with end-products (which are normally a multi-discipline team effort).
