Famous actors can use their fame to highlight the issue, and that's how it becomes a news story, but the issue affects all actors, especially the ones who are not rich and famous. They won't get their names in a news story.
If they are well compensated and have proper work conditions, what the shareholders and bosses are making is irrelevant. Market forces should determine their pay; otherwise, why do we think that they should make more money than anyone else?
So why does the net worth of Mandy Moore, et al., matter?

Residuals are due to market forces.
It feels like you should be arguing against causality0, not me.
Also, just because you've made a lot of money in the past doesn't mean you shouldn't speak up for the many many many many MANY people that don't or haven't (and might not in the future if the studios get their way!)
