You might want to visit Europe at some point. That's a very specific US problem. (Europe's not problem-free, but access to daycare/medical care/education is much easier to obtain there)

Sort of. It is probably better but if you don't have stable living conditions, which many people don't, that affects everything else. So you can say that people have access to daycare, but if you involuntarily have to move around a lot that is a real overall decrease in quality of that daycare.

Think outside your US bubble please. What you say is not even remotely true in most European countries.

Probably more like the top 10%.
