Traveling is cheaper in EU simply because more interesting stuff is very close, flights are crazy cheap (usually you can find flights under 100 USD both-ways inside EU), and you can do it a lot while being paid (20-30 days of paid vacations per year in most countries).

Retirement/healthcare and education is paid by taxes already in most countries so there's less things to save for. Also cars are optional and distances are smaller.

I agree about the rest (but I wouldn't want to live in US anyway, no amount of money can buy you a walkable city or safety for your kids).
