Not needed. Health care has a solution, and it's modeled after the HSA+HDHP plan most employees get now.
You can do private or public, but you have a high deductible insurance provider. They cover all costs after $X, you pay the first $X yourself. $X depends on income. For the dirt poor, it might even be -$500. You give them $500 for healthcare costs. They don't use it, they keep it, they do then everything else is paid by HDHP.
If you make $50k you might pay the first $4k of your own healthcare costs. If you make $100k, maybe first $8k. At $1m/year maybe you're paying the first $80k, and we cap it there. Numbers could be worked on.
Benefit of this is you will shop based on price for that $X and not waste money, but you won't go bankrupt if you have major medical expenses.
In return, eliminate Medicate, medicaid, employer insurance, most of the VA, etc... Overall of healthcare for country would actually go down, probably nearly cost neutral with what we have now.
