Yeah, but are they paying any of their own money to take care of those kids for two decades? As a parent, I’m involved in my kids’ lives on a daily basis and I’ve been given an additional set of legal responsibilities & obligations. Society expects more from me in order to raise my kids (though I did willingly take that on by becoming a parent). You raise a good point though that further muddies the idea, what about legal guardians or adults who help out kids, who decides who gets that extra voting power? And then with delinquent parents, why should they be entitled to more voting power? It also further disenfranchises the LGBTQ+ community as well, so yeah, it’s just fraught with way too many issues.
