Rumer Willis isn't exactly giving Mark Wahlberg a pass in the wage gap battle, but she thinks everyone's missing the point by making this about his payday.
Rumer and a friend were shopping Rodeo in Bev Hills Wednesday when she weighed in on the issue that has Hollywood and America pissed off ... Mark getting $1.5 million, compared to Michelle Williams getting less than $1,000 for "All the Money in the World" reshoots.
It's worth noting ... Rumer's mom, Demi Moore, was one of the first women to earn an 8-figure paycheck for a single movie, so ya gotta think she's been schooled on wage disparity in Hollywood.
Her take? Back off Wahlberg ... attack the system!
