"Not everybody" is definitely a thing, no doubt about it. But citing the minority as the default is a dishonest argument, too.
Let's say your kid has a kid and they're local. Do you want him to personally do right by that kid through thick-n-thin or not? Are you willing to work in support of raising that kid or not? As a potential grandparent where does that kid rank in your own hierarchy of priorities?
Sloughing any aspect of that's child's welfare off on the state instead of family is in no way responsible or virtuous. Reliance on the state is the temporary fall back position in extremis, not a career choice.
Advocating for improvements in the current parenting dynamic is not "going back". It's "going forward". We want more functional kids, not less. By comparison the parents' personal interests are entirely subordinate to those of these kids. Nice if you can also pull that off, too; but ultimately an add-on accessory, not the primary orientation. That means you work the job you hate if that's what it takes to TCOB. It means you stick around and hang out with the kid instead of going out and partying if that's what it takes. Etc.
This is all basic. It should go without saying. So why do we have to explain this to you? How could you not already understand this?
