Some women can't use hormonal contraception. Some women use contraception and still get pregnant. Some people make mistakes, because they're human beings and none of us are perfect. And if that a person is pregnant and abortion is not something they can accept they still have no option other than to continue with the pregnancy. In any case - when people want a child they engage in wishful thinking. We all do it. People have children when they have a cancer diagnosis - do you think that's immoral? That makes them a bad person? Or when people have an older child with complex health needs? We hope we can cope, and that life will get better. We'll find a better job. Our cancer treatment will succeed. We'll get support from family and friends. We'll find a cheaper home. Again - people don't behave like robots when it comes to decision making about the things which are more emotionally important to them.
"I am not saying you cannot raise well adjusted kids if you're poor. I am saying you cannot raise well adjusted kids when you know the state won't help you after 2 kids, yet you continue to have yet more kids you can't afford, driving your existing kids into poverty. Different if contraception is not available, but it is."
Except the evidence on the two child cap shows that most people weren't aware that they wouldn't be able to get help from the state to care for their additional child should they need it. If you'd read the research on the two child cap you'd know that, but you don't want to read it because the experts from both sides of the political spectrum have examined the evidence on how this policy is working and said - it doesn't work, it's causing suffering, it's harming children. You've got an idea in your mind and you're sticking to it, regardless of the evidence.
"Why do you think the state has more responsibility to these children than their own parents? I just can't get my head around that."
But we accept that the state steps in when parents can't or won't care for their children. It's a basic principle that drives a lot of public policy, because it makes the welfare of the child central to the social contract. Your take on this is - yes, we know this change in policy will result in long term harm to the child, but we that's not our problem as a society.
BTW - your thinking is very common in the states, including when it comes to things like healthcare. 'why should the state have responsibility to pay for your healthcare or your children's healthcare?' The whole right wing rhetoric around personal responsibility is toxic.
"My own family (both sides) were poor. Mum was brought up with tons of siblings by an alcoholic mentally ill dad. Her mum died when she was 4. Dad is from a council estate and he has more than one sibling."
What's the point of this little bio? You think it gives you moral authority when it comes to justifying why the state shouldn't offer the same sort of support to children living in large families than it extends to children with fewer siblings?
