Oh, the horror! Going to the doctor once a year for a physical!
Doesn't sound like much of a burden to me. It actually makes good economic sense. People who blow off preventative healthcare, cost the rest of us money - through increased healthcare costs and premiums.
A universal healthcare system requires shared responsibility. If you're going to require employer to provide healthcare insurance (which edwards plan does), you have to reduce their cost by requiring people to get preventative healthcare. Give both employers and employees shared responsibility. One of the biggest costs of our current system, is that it focuses on treatment, and not prevention.
Oh, and no one is going to jail if the refuse to go to the doctor. Edwards plan simply rewards those who go for preventative checkups, and sign up for healthy living plans, with lower premiums. If one is too fucking lazy to go to the doctor once a year, they'll pay higher premiums. That's the sanction. They're not going to be arrested. Makes sense to me.
