Does the Massachusetts Institute of Technology have a gender quota?

Well, when you look at many of the top positions at MIT from the president down many of them are held by women. Were these women chosen on merit and/or some kind of gender quota (explicit or implicit)?

Men watch out! In the battle of the sexes, each sex resorts to what they do best! This is about power and dominance! Women want leadership roles but not gender equality e.g. in the construction or mining industry! Let men do the sweaty and dirty work!
