I seriously doubt that the majority of parents want the state to raise their children for them.
By arguing about irresponsible or lazy parents you are latching on to the first, most convenient thing that seems to make sense to you. But I think that is a mistake because not only does it perpetuate some kind of distorted sense of reality where parents don't care about their children and want to hand off all responsibility for them, but it distracts you from the real causal issues.
The fact is that humans have for millions of years acted in various levels of coordination to raise and look after children as a group. Modern society has made this all sorts of dysfunctional, but it still exists.
And THAT is the problem that they should be tackling.
We did that for a reason and it is undoubtedly better than the alternative.
Either way, if parents had more time to raise their children rather than slave away at jobs to stay above water, I have to think there'd be some improvement in child development.
Long working hours and both parents working full time means they do not have the time or the energy. Then you have the state offering help, and encouraging parents to drop them off at school first thing for breakfast club, and then keep them there for after school activities.
This is normal and what public education is for. Teaching online safety and sex ed should be considered no different than teaching history
