A basketball player can make quite a bit of money playing basketball if they're exceptional. Looks like the national average for a plumber is about $60K/year. Most people on this forum would scoff at that if someone offered them that. It's actually about as much as my uncle, a heavy diesel mechanic, made before his untimely death. It's about what my father made when he retired.
