The best argument for a single-payer health plan is the recent decision by giant health insurer Aetna to bail out next year from 11 of the 15 states where it sells Obamacare plans.Aetna’s decision follows similar moves by UnitedHealth Group, the nation’s largest health insurer, and by Humana, another one of the giants.
All claim they’re not making enough money because too many people with serious health problems are using the Obamacare exchanges, and not enough healthy people are signing up.
The problem isn’t Obamacare per se. It lies in the structure of private markets for health insurance – which creates powerful incentives to avoid sick people and attract healthy ones. Obamacare is just making this structural problem more obvious.
In a nutshell, the more sick people and the fewer healthy people a private for-profit insurer attracts, the less competitive that insurer becomes relative to other insurers that don’t attract as high a percentage of the sick but a higher percentage of the healthy.
Eventually, insurers that take in too many sick and too few healthy people are driven out of business.
If insurers had no idea who’d be sick and who’d be healthy when they sign up for insurance (and keep them insured at the same price even after they become sick), this wouldn’t be a problem. But they do know – and they’re developing more and more sophisticated ways of finding out.
