I think I was clear that I didn't endorse their lifestyle/parenting style.
I am pro the continuation of humanity.
I don't want extinction.
It's one of the reasons I had DCs myself.
I talked to my teen about this.
They said most teens don't want DCs as they don't see how they will afford them, don't want the impact on their careers/ finances/ freedom.
I think we have a societal duty to make parenting as easy as possible so every woman can have the number of DCs she wants (most don't).
We can have more ethical lifestyles that don't do as much damage to the environment even with large families eg not flying, not driving, not eating meat.
The dependency ratio problem isn't just about paying care home fees. That's a fraction of the taxpayer cost of old age. Most NHS spending is on the elderly. Most council social care. Most of the benefits bill is on pensions.
If we don't increase the birth rate or immigration we will need drastic policies other countries already have such as fees for GP/ambulance/A&E, care home fees being means tested on the adult children, no non means tested state pension, lower public sector pensions, no long term social housing, capital gains tax on own home etc.
I don't want any of this!!
