So what's next? Do we compensate children for playing nicely together because they grow up to be caring citizens?
That's not "next," it's been happening for generations. We pay taxes, whether we have kids or not, to support schools and community programs that teach children to "play nicely together," among other things, and help them grow up to be knowledgeable, caring citizens.
- Employers are compensating stay-home parents. The worker gets paid enough to provide for his/her family, otherwise both parents would need to work.
Workers with a stay-at-home partner caring for their kids, at least officially, are not supposed to get paid more than workers who don't have kids, or don't have a stay-at-home partner.
In reality, men with children actually DO, statistically, get paid more, controlling for other factors, than men without children -- perhaps because of unconscious assumptions that these men need the money because "they have families to support." Women with children, meanwhile, get paid less, statistically, than men or women without children -- perhaps because of unconscious assumptions that they'll prioritize the children over work. Either way, though, I don't think most people would consider this a fair arrangement.
Beyond that, employers who offer retirement plans create the possibility--in the event of the death of the employee--for the stay-home partner to obtain funds that were generated by both the company and the employee.
Some retirement plans end with the employee's death. For this and other reasons, older women in poverty far out number older men.
- As far as volunteering goes, non-profits (correctly) tell us about the benefits volunteering brings to the volunteer. Volunteering offers (among other things) the opportunity to help one's community, positive human interaction, and networking possibilities.
Paid work offers psychological and networking benefits, too. And yet we pay people to do it.
