Yeah it is. Not a new solution, but a solution. Private insurance is far superior to medical welfare in every way.
Carson's scheme is a $2000 payment to an MSA with one third of that going to a disaster-type insurance plan and the remainder to medical-related costs like co-pays and the like. So the first question I would have is in what world can the average person buy even a policy with a $10k copay for less than $700 a year. The second question is that how does someone cover a $10K copay on $1200 a year?
But let's look at that as a replacement for Medicare. Does anyone honestly think that medical coverage for an elderly person could be covered for $2000 a year? Honestly? An 85 year old Alzheimer patient covered for $2000? A 70 year old with diabetes and a heart condition for $2000? Really?
