No, I have not conflated two different problems. I have introduced the other side of the same problem.
No. These are NOT the same problems.
In many respects, insurance works best if neither the insurer nor the insuree has any information about how their risk differs from the general pool. Everyone thus has equal incentive to buy insurance, and insurers have no reason to price anyone's insurance any differently. But that's not the case in healthcare, since pre-existing conditions mean some people will be known to be high risk. This is an information problem. It exists
regardless of income disparities.
Conversely, even if we had no information problem, the ability to pay even a common insurance premium would differ from person to person. This is the equality problem.
These are two different problems. You did indeed conflate them.
You have not answered my question. You have rejected the concept of people paying in in proportion to their abiity to pay. You have mentioned paying according to the level of benefit you would like to receive. Sounds good, but what does it mean?
It means keep the system primarily market-based.
If you have very limited means, you decide you don't want to be covered for cancer treatment, or a heart bypass? Then what happens if you need such treatment?
I would like insurance to be priced such that people of limited means can still get coverage for serious conditions, even if it means some government assistance. I do not want a system where you don't have to pay
anything and still get full coverage.
Assisting the "poor" is all very well, but first that gets you into a lot of expensive means testing, and the clear temptation to fraud.
It doesn't have to be very complex. Hell, the IRS already does means testing on basically every taxpayer, no reason you couldn't use that existing infrastructure.
And second, it leaves those just above that poverty line in a very bad position if they happen to need something expensive.
That presumes some abrupt cutoff. One need not do anything of the sort. There are plenty of ways to phase out benefits over an income range. Again, the IRS already does this.
How are you going to determine what each citizen contributes
I don't intend to. Which is part of the point: I don't want a system where someone determines how much everyone pays. Centralized planning doesn't work very well for large, complex systems. I want individual choice about how much someone wants to pay: if they want more coverage and more services, they can pay more, and if they are willing to accept less coverage and fewer services, they can save money by doing so.
in a system designed so that everyone will receive the healthcare they need, when they need it?
Don't kid yourself: there is no such system. Healthcare, just like almost everything else with a finite supply, will
always be rationed. Some people will
always be going without healthcare they need.
