even if they can fix the website, ObamaCare itself will never work
Actually, it could if they're patient. If a person is allowed to sign up when they need it, but once you're in you can never leave (to paraphrase an Eagles song with I believe was about an insane asylum) it'll be like an income tax deduction, but increasing at the whim of insurance companies. It'll destroy medical innovation, it'll decrease spending on things besides medicine, and it will probably kill people while they argue with their insurance companies, wait for appointments and approvals, and deal with things like being away from the exchange when they get sick.
Nobody's thought this out. Is there going to be an underground of self-healers who totally stay away from the forced nature of the system? I hope so.
