There are very important emotional aspects to parenting that you people who constantly complain about feminism seem to completely ignore, I'd much rather have a father who's there and who I can spend time with than a father who's working two jobs because "more money earned == better parent".
Now try that if you are under the mean. Good luck. It is absolutely the case that SOMEONE has to pay the bills. If you are making 40-60k and alone you can live pretty ok, now try that with 3 kids.
Making so much money you can afford to relax, take time to hangout with kids, take them skiing, buy PC for them, take them travelling, feed them good food. Put them in school where they will make connections for the future. You will absolutely makes a better parent, period.
There are more effective ways to help poor people than special paternity clauses/bonuses etc.
1 in 7 children in America may not know where their next meal is coming from. Many children live in unsafe neighborhoods.
I think perhaps a better way of putting it is that men are primarily responsible for the lower tiers of Maslow's hierarchy of needs while women are primarily responsible for the upper tiers. Obviously that doesn't mean a man can never change a diaper or a woman can never pay a bill.
It's high time that fathers start putting in some more work in that department too. Sweden has 480 days of paid parental leave, and each parent has exclusive right to 90 of those days. Have fathers spend some time raising their kids instead of just letting their wives do it and you'll see that things should get better.
