IMO, the best thing that SAG-AFTRA members could do would be to fully embrace the labor v. capital narrative & use their social media & other clout to portray themselves as brothers & sisters in arms with all laborers.
This will help temper attacks on them as just a bunch of entitled rich actors who are fortunate enough to even be in a union.
It is the perfect opportunity to get desperately needed media coverage on the importance of the labor movement. I hope they use it.
