presume:
- the medical provider infrastructure continues to function largely as-is. that is, doctors seeing patients, hospitals taking them in, etc.
- all the providers get compensated - ie, doctors get salaries or bill patients if in private practice, hospitals bill sufficiently to cover costs- physical plant, nurses and staff salaries, REASONABLE salaries to administrators
- instead of payment being processed through HMO or for-profit insurance company, it is processed through a not-for-profit. Could be government staffed, could be something like the "Blues" (they are still technically not-for-profit, but top people make a lot of money) with govt regulation
- sufficient revenues are collected to fund these payments, and the processing of them
You have removed from the equation the obscene profits that go to multimillion dollar bonuses and dividend payments. You have reduced the overall cost of healthcare. You add those not now covered, who usually get some level of care now via expensive emergency rooms, often unnecessarily expensive because they could not get early care. This both further reduces costs AND provides better care to that population. It reduces costs because it generally gets provided today expensively and inefficiently and funded by either government or higher premiums on those who are covered.
The net result is less outlay, less cost. Administrative waste in fighting claims is eliminated, excessive profits are eliminated, everything else stays the same, but better.
Collecting the revenue to fund it will pull wealth from the general population but be more than offset by eliminating the costs on companies and individuals who now pay. It will be a stimulus to the economy - auto manufacturers will be better able to compete, individuals have more to spend. The rich few now sucking the rest of us dry are the ONLY ones hurt. And they are the ones paying for CNN's hit job.
All arguments against it are red herrings. Any issue or deficiency in a working system can be analyzed and corrected, if the system is fundamentally viable. The one we have now is NOT viable, because the drain of wealth from the many to the few is destroying our society.
