The fact that women as a whole make less than men as a whole (an income gap) is continuously portrayed as women doing the exact same jobs as men, with all the qualifications etc, equal, being paid less than men ( a wage gap). This misrepresentation has been going on for decades now and used to drive all sorts of policy and political action. So I'd say your comment applies in virtually all situations with respect to MSM for say the last 40 years.
