I give a rat's arse about maternity leave as an argument for the inequality of salaries. Not all men make the same salary, so what.
If you don't like the level of your income, bust your hump and make what you want. Only in America do you have the right AND the opportunity do do that.
My husband says men think about sex every 28 seconds.
It sounds to me like you should do more and think less [just being considerate, don't get all testicle] ;op
