Insurance is a bet for the person taking the insurance, not the one offering it. Just as casinos are not gambling. Law of large numbers and all that.

I agree that it's a weird business to be in (and certainly the US has not figured out the best approach), but this article is about Germany, and generally I think we strike the right balance here. Not in every detail, there is still a lot of room for improvement (too many insurances, too little competition between them, some questionable decisions about reimbursement) - but I wouldn't dare to claim that I could consistently make better decisions.
