I don't think these compare in that way. Besides that, based on proper study (referencing "the invisible gorilla" here), human beings are terrible at a lot of cognitive tasks which are fundamental to what you are proposing. So no I am inclined to disbelieve anything which has "common sense" as a basis, or at least I challenge my human reaction to believe it. 

Anyway, we know _from research_ that men have, on average, more muscle power. So on average men are stronger, but a lot of women are stronger than a lot of men. And wether that's beneficial depends entirly on the goal you're trying to achieve.  How much they work together etc etc. So the statement is arbitrary at its best. Wether or not you vote democrat or republican based on your hormonelevels are, is of quite a different order of impact on society if you ask me.

Wether or not tax dollars should be spent is a political choice.
