I think the main factor is how many kids you have.
No kids: USA > Europe
1 kid: they are similar
2 kids or more: Europe > USA
In the USA each kid is an extra 3000 usd a month expense at least, more if one goes private and include university tuition.
How parents can pay for two or more kids’s education in USA (or UK) is beyond me.
With two or more kids in USA you essential force your children into wage slavery by going into huge amounts of college debt.
