Yup exactly.
There was an actress not too long ago who broke down her financials. She said her 14-year acting career to that point has really equated out to about $150k/year after all the taxes and extra people got their's (which probably is a little more in Hollywood/glam industries).
However, agents, lawyers, personal skill trainers, etc. Maybe you need a special doctor. Then extra things like acting coaches and the like are all things a player might additionally spend on. The extra house out in LA that you also pay people to maintenance, the extra house that you buy for your family/friends, the cars, etc.
Then yeah, 1 or two kids/drama, cost of living if you're in an expensive city, etc. and your salary starts to look pretty so much so to the point that one or two bad decisions may jeopardize what you have.
