I was going to say this. We have this weird habit in the West of trivializing raising one's own children, as if that's not "real work". A lot folks would rather raise their children instead of outsourcing it to strangers just to work a job they hate.
Many of us (and by “us,” I mean “mothers”) see it as a balance: I am outsourcing part of my child’s upbringing in order to maintain a career I like well enough that’s capable of supporting us both should life throw some curveballs at us. Say “life insurance” all you like, and my response is “unpredictable inflation”.
I don't think anyone is trivializing it... but the government can't tax homemakers to pay for medicare, pensions, and other social services which is the relevant point of the discussion.
Raising children might not be what people are best at, and it's more efficient to work a job that can pay for this stranger, and to have money left over.
There aren't many qualities that disqualify a person from humanity, but being so bad at caring for one's own children that an employee would do a better job might be an example.
you can't pay someone to love your child. only you and your partner can love your child. love is nearly as important as food to them. and you have to show that love in the attention you give them - tucking them into bed at night isn't enough.
