No suspicion when a man wants to work with children
No sarcastic remarks about male nurses
No "you can't play with that, it's for girls"
No teaching little boys that to be a man is to be tough and hard and unemotional
And of course all the women in a man's life will be much happier
--
Of course they won't get disproportionate amounts of pay and won't be chosen for promotion unless they actually are the best candidate, but I think the above makes up for that.
