People really need to think about this. How much would we save at the individual level with a real deal like this, and at the societal level when taxpayers no longer have to pay increased costs for all the people who waited until death's door because they couldn't see a doctor at a sensible time?
If I could pay for that kind of guaranteed-for-life coverage in the U.S., with $0 deductibles, $0 co-pays, no maximums, no reimbursement paperwork, no excluded conditions, etc., for only 15% of my income, I'd gladly do so. In California, I spent around 7-8% just on my comparatively shitty health insurance + out-of-pocket, which had several exclusions and no guarantee I'd be able to renew at a similar rate if I got sick. So I consider the Danish offer a real deal. Even more so if your medical history has any major blemish on it, in which case U.S. premiums skyrocket to much higher than 15% of a typical salary.
