It sounds stupid, but women’s rights were reversed in a drastic fashion in Iran and other countries in the 1970s-80s.
When countries’ social orders are under stress, weirdos sometimes take over — and when weirdos take over, sometimes they think throwing veils on women will solve the problem.
I don’t think it takes much imagination to figure that a hotter, drier, poorer world is one where women will be scapegoated and thrown into the kitchen barefoot more often.
