It feels like you’re saying wealthy people and those without disabilities should be able to do what they like. But everyone else should have to take responsibility for themselves - you say those with mental disabilities should just take responsibility for it, you want to reinstate the child benefit cap if both parents are out of work so presumably they just have to take responsibility for the children they have if they lose their job, and cut carers allowance… etc.
Are you perhaps in a bubble of an existence on these issues with little empathy for anyone else (assuming this isn’t a bait thread). If you’re truly interested in these issues, and early years, why not look at the clear research on the benefit to society of lifting children out of poverty (more likely to complete education, join the workforce, less likely to end up in the criminal justice system, have better health etc). ‘Punishing’ parents for being out of work assumes it’s a choice, and if it is and they are really feckless parents then it will mean that child does not eat.
I’d also suggest volunteering to see these issues in action - try a food bank to open your eyes.
Paying a parent to stay home takes someone out of the workforce - exactly what you object to with the poor or disabled. This means less economic growth - this then raises the obvious question of how you are going to then pay for this policy.
I’m not saying it would be nice for everyone to have the choice to stay home…. But in all honesty is this because you’d like to and feel you should have the right to. I think lots of parents would like to (a big part of that must be so they can have that time with their children). There’s a lot of research on outcomes of children with working mothers - generally educational outcomes are the same as stay at home mothers, for girls it’s higher, for boys it found these are more likely to be competent and equal in the home (with childcare/housework) https://www.library.hbs.edu/working-knowledge/kids-of-working-moms-grow-into-happy-adults two parent working families are more likely to be financially stable and poverty is one of the biggest influences on outcomes for children.
I think you can campaign on these points if you want and they may be popular in the divided society we live in, but I do wish people would be more honest about their drivers - I doubt given your other views that there’s much altruism and hope of helping wider society. If you did wouldn’t your focus be on better early years provision for all?
