Women cans.
If women ruled the world, then there would be ten times as many female washrooms. Can't exactly just pull down a fly and let it rip in there.
Also the airplane overhead storage bins would be lower, so it is easier to put our carryons inside.
Also hairdressers wouldn't be allowed to charge highway robbery for a female cut. It takes the same amount of time as a male cut, but instead of $10, it is more like $85 for a female style cut.
