“Rock star”
LOL!
Very, very few rock stars are millionaires, unless they’ve been in the game a long time and have a couple huge hits - and even then, a lot of them blow through the money in a couple of years.
You’d be surprised how little some very famous musicians actually make.
Same for actors - there’s a lot of pretending going on, and the majority of actors probably make a decent solid middle class living, perhaps close to 100k, but they make up for it with freebies and per diems while working, and having most of their meals paid for while they work.
There’s only a small handful of actors and musicians who are “rich”, and tens of thousands, if not more, who are happy to make 40k a year.
So, I guess the idea is to be one of those rock stars who have a dozen or so hit songs, and make a lot of money.
