Although it is really just pushing around how other people/taxpayers are paying presumably the same total cost for high-cost healthcare users, isn’t it?
That is, we pay for others with our premiums or we pay for others through our taxes.
And yes, taxes are the better route if that is the choice.
The advantage of getting the uninsurable out of the insurance pool is for us. Insurance companies are taking it out on those who aren't high risk, with high deductibles and restricted care options. They have to keep costs in line where ever they can.
