What does it mean to say that women are "institutionally lower-status" than men

GIWIST. (*)

I would buy "there hasn't previously been a male counterpart to the feminism movement because males as a social class have (almost) never been disenfranchised" as an argument. (Not necessarily a correct one, but a testable one. My possibly flawed assumption, prior to any fact-checking, is that the feminist movement has its roots in the women's suffrage movement.)

Once more, "status" here seems to only muddy the waters, and invite a definitional argument starting here which goes nowhere close to answering the original query.
