I think that’s grossly simplistic (and arguably sexist). The idea that you can assign a simple value to mothers or fathers is flawed in itself. The relationship between parents and children is arguably the most complicated human relationship there is and the number of ways in which both parents can and will influence the child are almost infinite. Also, there will be massive variation between different families and different individuals.
Grossly as in disgustingly or over-all?
It is not a generalization over mothers, it is meant to support one of the usual cultural roles of mothers in my culture. It is meant to encourage mothers to care for their motherhood. Ultimately it does not really matter as long as we get a community with a strong bonds, as we actually do.
The thing is woman =/= mother (even potential mother). The idea of all women getting paid more because some women will have children is obviously flawed. The correct approach (and done in many countries) is to have systems and procedures to support working women and men who become parents. There is no reason to treat workers who aren’t having children differently on the basis of their gender.
As an intensive, I see it is far from a flow. My point was to support possible loving potential mothers instead of having the possibility of hurting them for good things they want to do. It is not a woman's fault that she can't attend because she's having a delivery. The community should support her, including employers, so she does not get hurt for something honorable she decided to do.
I’d suggest “differently” rather than “more”, just as the parents will love each other differently to how they love their children (we’d hope!). It’s also worth noting that nobody is average. Again, every relationship is different.
Yes, a valid argument.
