One thing, which I don’t think has been mentioned previously, is the cost of sending your kids to higher education. No real direct tuition cost in Europe, while in the US $100k/kid seems to be the norm and something most parents have to actively save for. Sure, there may be cheaper avenues such as online courses, but no matter who you twist it, higher education in the US is pricey. Maybe not a deciding factor, but still to be considered.
