Would that $2,000 a year be put aside for medical care when one turns 65? Because if they contribute for 45 years, that's only $90,000 for insurance when one is retired. Don't know how that could work, since some people would need next to none of it while some others would go through it in a few years. What happens when it runs out? Do they let people die?
Like a lot of what Dr. Carson says, I'm not sure the details work out real well. A better answer would be a plan which has people seeking inexpensive alternatives to standard medical care.
