Why do rich millionaires still choose to work?

For example, Pete Davidson’s sister is a physician assistant, even though her brother is a Hollywood millionaire. Why work?! If your brother is famous for fcking Kim Kardashian and cruising on $100-million dollar yachts with Mr. Beast, why would you ever in your right mind choose to work?? At that point you’re not a regular average person anymore. You have everything in life!! Man if I had a Hollywood millionaire in my family I’ll happily stay my ass at home! Fck all that clocking in, clocking out bs!
