It depends entirely upon how it is obtained.

Generally you are correct that a certain level of worth is unobtainable without being a horrible human but not always. As I said, there are many athletes who are working class despite earning many tens of millions.

I very much consider Muhammed Ali a revolutionary comrade for example.

You should focus less on their total income and more on how it is made. Class is what matters, and while class generally forms along the lines of rich vs poor this is a reductive simplification of marxist thought.
