I just saw a podcast about a startup that was working with Medicare/Medicaid to reduce costs by improving preventative care [1]. They look for people at risk, target them and take a cut of the overall reduced spend. If Medicare is requiring the same outcomes and disbursing per-person based on the cost to Medicare, then the insurance company's profit would have to come from either selecting for healthier people on the input side, or keeping them healthier for longer. Selecting for healthier people might be hard if it's "all signups allowed". That sounds like a good thing.
