Just to make comparison even more complicated, I assume in Switzerland you don't need to pay as much for health insurance, and put as much money aside for retirement, and people in US do. And I know college fees in Switzerland are around 1000 to 3000 per year, not 10 000 to 40 000 like in US. So if you have kids, you don't need to save for their college. (...But then you can only send them to European universities. If you want to send them to a US university, you still need to save money for that.)
