Earlier quoted context omitted.
This is true, I'm in a community that values having a parent at home with the kids. Many are on wages most would expect make it impossible but they live good lives. Some very small business owners, charity works (earning very little) and a few high paid professionals.
Stay-at-home parents do a lot of financially valuable but unaccounted work that can come quite close to improving the family finances almost as much as if they had a job near the median salary.
At 16k per child per year, one or two kids is equivalent to one or two persons making minimum wage.
