He's part of the labor, yes. Do you think he's 100 million dollars worth of the labor? Because the answer is obviously not. Again, I don't fault the young actor for making his bag in a system that he didn't build but now he's got 100 more million than he did previously and now he's responsible with how he uses his power.
Labor deserves more money and the owning class far, far less - yes. How many VX artists worked this film and how many of them are working reasonable, heathy hours at a thriving wage with good healthcare and good vacation time? How many grips and costume hands and makeup artists and and and ad infinitum that aren't making money commensurate with Tom Holland's pay rate and is that fair? Dedicating your life to a film for a year is definitely worth a premium, but not such a premium that other people suffer and that's my only point. It's the same thing as CEO's. 100 million is 20 people never working again for the rest of their life, or 1000 people making a decent wage for a year. If he made 100 million 1000 other people didn't get a fair wage (or didn't get a fair portion of the profits if we're being generous).
