Though maybe it gets even better than that and we just all start wearing watches again.
I want that feature but I'm not a watch wearer.
Right now, the right choice is to combat this problem before it becomes a real problem. Before it sets root as cultrually acceptable to hand over your biometrics data to private companies without the right payment and compensation.
I agree with your premise about the point of insurance. How is the discussed idea any different than insurance companies giving different rates to older people and denying coverage for pre existing conditions, in terms of discrimination against the non healthy?
Incentives to make people healthier should not be a problem with these constraints (max premium rations and guaranteed coverage for everyone). It’s no different than offering a lower car insurance premium to someone that doesn’t drive drunk.
Though there are still questions of how strong the firewall is in cases where the Wellness programs and Insurance providers share parent companies or even just C-Suite members. Arguably, the separation allows corporate plan buyers to pick and choose Insurance and Wellness program separately, allowing for some competition between them on things like privacy. Yet, being employer-driven "benefits" first and foremost, it's hard to say how much the end consumer/user/employer's privacy is always prioritized, as it is an indirect need of the market.
(Also, every employer I've seen the Wellness program didn't define HSA contributions but rather "discounts" on Insurance premiums, which does seem to indicate that Insurance companies are probably using the Wellness program for risk pools, even with what little data they supposedly are being fed across the firewalls.)
