You personally pay around that amount in "insurance", but a big part of your healthcare costs are being taken out of your general taxation. The Netherlands spends around 13-14% of its GDP. That's pretty far from 100/EUR/month per person.
I live in The Netherlands and I'd take Western European healthcare over the US's any day, but let's not sugar coat it by hiding the ball about how it's being paid for[1].
Before I moved to The Netherlands I paid 0 EUR/month in "health insurance" (a country with a true single payer system). Does that mean I wasn't actually paying anything for healthcare? No.
