A 6 figure salary in the Bay Area is not what most people would call "rich", in some areas you can qualify for subsidized housing with a 6 figure salary and a family of 4.

And while I may be biased by being a decade older, "mid-forties" doesn't seem old for a senior manager.

In any case, unless someone is truly wealthy, you can't say "Oh well they don't care about their job because they are rich", because they need that job, and if they are a poor manager, they'll lose that job.
