@HannaYeah I don't need to find you an example that bucks your stereotype. I was that single parent, and if I hadn't met dp, still would be. I was also, shock horror a young single parent. Sorry for not conforming to your preconceived idea. You wouldn't be the first taken by surprise that a single parent can provide and raise a child as well, and in many cases better, than a couple.
Meeting dp made zero difference to either of our budgets or parenting abilities.
I'm also sorry that you can't see beyond your own experience. My parents were happily married and ticked every box for being ideal parents. Suffice to say my childhood was hell. Yet it doesn't cross my mind to assume my experience is representative or that the dc of outwardly similar parents have the same feelings I did.
As for role models, single mothers are statistically far more likely to work than those raising dc as a couple. And ime far less likely to conform to gender roles at home. And regardless of income, I'd say that's a far better influence than a mother that doesn't work and relies on a man to provide, with any division of labour clearly defined as women's work and jobs for a man.
Agree with pp's about the difficulty and enjoyment. Because some would be incapable and unhappy without hubby at their side it doesn't mean everyone feels the same way.
The 'ideal world' scenario of a second parent is bullshit. Four grandparents, an extended family of aunts, uncles and cousins, all healthy and active might also add something to a child's life. So anyone without siblings and both parents alive and healthy shouldn't have dc either. Oh, and as active grandparents are the ideal, most older parents are also ruled out.
Being white, British and financially comfortable also statistically leads to better outcomes, so anyone not meeting those criteria shouldn't have dc either.
Independent education also statistically provides a better outcome, so only those able to provide it should reproduce.
The mothers level of education is also a big factor in outcomes, so ideally only those educated to at least degree level should have dc.
Wealth would also improve childhood experiences, so only those capable of providing a very privileged upbringing should 'ideally' have children.
And a mother married to the father is no different to any of those other unnecessary ideals.
