One of Obamacare’s many problems was that it created a high loss “pool” on the exchanges, composed of those who were unable to obtain insurance due to health problems, those for whom subsidized insurance was less expensive than purchasing insurance and those would had no employment alternative available to them. Possibly that was realized at the beginning, perhaps not. It assumed that those with preexisting conditions (some catastrophic) would be ‘balanced out" by young, healthy people. That “balancing” did not happen because so many young people either a) are employed and have employer coverage, or b) remain on their parents’ plans longer, or c) don’t get insurance at all.
In addition, the insurers appeared unable to properly underwrite the risks in such a pool, unduly concentrating as it did those who have health problems in a seemingly unpredictable manner, and began withdrawing from the exchanges altogether.
And so, the government is faced with two choices (at least that I can see). One, which some say was the Democrat plan from the start, is to force the entire nation into one pool through “single payer” government control of medicine, and the second is to allow a free market but provide additional support to those who are otherwise uninsurable.
The first does not fix once central problem with Obamacare in that it forces one segment of the public to pay the entire cost of another segment as well as its own. The second might have problems of its own, but it seems so far unexplored.
Medicaid, as we know, is available only to those (other than those pushed into it by Obamacare) who have virtually no assets other than fairly low level equity in a home and a vehicle. It is, therefore, “means tested”. With “single payer” there would be no “means testing”, meaning that persons with substantial assets and income could still have healthcare provided largely by other payers.
Some societies find that acceptable. Others provide a sort of “safety valve” by allowing both public and private sectors. Even those systems provide a “welfare” kind of system for some without any “means testing”. It is just part of the concept that the whole of society owes medical care to everyone without regard to whether any of the members can afford to pay for their own care, either privately or by insurance. Indeed, that’s what Medicaid does, but to a more limited extent. It is a benefit provided by all, to a few who cannot otherwise afford it. A big question, then, is whether all should provide the benefit to the few, some of whom cannot afford it, as well as some who can.
