And here you said that insurance companies would leave the business before doing such a thing, and yet, every job provided health insurance plan I ever had came with a set price.
Every job provided health insurance plan covers healthy individuals, which are the bulk of workers. The larger the company, the larger the pool, and thus the smaller effect an ill hire would have on the plan costs. Some states allow employers to pool together.
At the end of the year, every pool - every single pool! - has its premiums adjusted so that that pool is profitable to the insurance company. If your company consisted of 10 people all with MS and nobody else, then your insurance costs would be astronomical.
When somebody enters the pool with a pre-existing condition, they are effectively punishing every other member of the pool with higher rates without having paid premiums while not needing care.
Oh. I get it. So the insurance companies are not allowed to deny coverage based on existing conditions, but there is nothing wrong with them charging premiums, of say, one hundred billion dollars a month ($100,000,000,000/mo).
That depends on what you're talking about, you keep changing context.
If your context is your proposal: Clearly not, because being forced to cover all comers regardless of pre-existing conditions or coverage at flat rates while not requiring the cheap-to-cover healthy individuals to pay for coverage would cause rational individuals to delay coverage until needed, requiring insurance companies to charge astronomical rates people like you wouldn't "allow", thus ending the potential for profit and the insurance companies would leave the market.
If your context is the "Obamacare" reconciliation bill: High cost individuals will be placed into high risk pools that is subsidized by the gov't. The insurance company recoups the value spent by the high risk pool on medical costs, the gov't subsidizes to the level it is willing to, and the balance is billed to individual policy holders.
Existing state policies for high risk, such as California's Major Risk Pool pools the high risk patients with Cobra and other state sponsored medical coverage, and then subsidizes coverage on top of that. This is the only reason a group of guaranteed cost individuals can be covered without massive premium costs.
Once again, insurance is a profit making enterprise. If you are intent on eliminating the possibility for profit by requiring low cost coverage to high cost individuals, thus allowing low cost individuals to escape the market due to lack of need, then the insurance providers will be vacated by profit seeking companies.
See, that way the insurance company, say Humana, can claim that they offered coverage, but the customer refused to pay, which is required by law. They were so kind as to give the number to Cigna. Their rates are half of what Humana's are for preexisting condition customers.
$50,000,000,000/month is still a profitable enterprise, even for a pre-existing condition. Of course, yearly caps exist - until "Obamacare" is passed, so the actual price point would be much lower.
See, an understanding of how insurance works is necessary to design reasonable proposals for reform.
