> you've cleverly argued in a way to make hidden the major point i wanted to make - which is that insurance companies making a profit is a loss to the payer. I'm purely talking about the insurance system, and not the medical provider system (hospitals/doctors etc).

But then you're not addressing the majority of the problem, because insurance company profits are only a single digit percentage of premiums.

And even the "profits" aren't all waste, because you're paying money but not getting nothing in exchange.

If you want to have patients not paying directly for care then you need somebody to process claims, and those people need an office to work out of. The investors in the insurance company paid for that office. A lot of their "profit" is just the internal rent being paid on the building. If you move that function to the government, the cost doesn't disappear because the government still has to pay for buildings to operate out of to process claims payments to providers, which had previously been paid for by investors in exchange for profits.

Health insurance companies don't generally produce above-market returns on capital, so there is no real evidence that their "profits" are introducing any avoidable cost at all. It's just a method of paying for the things the investors' money bought.

Heck, there are non-profit health insurance companies that make no profits. Where are the savings, if some existed? (Answer: They still had to raise capital, but they used loans or bonds or spent labor begging for donations instead of selling shares, and that turns out not to be much different in efficiency.)

> so therefore, insurance companies will pick out the least risky people, least unhealthy, and not allow the sick into their programs. That is exactly what you see today, because those more ill people are what saps the profits.

The premise of insurance is that you don't know who those people are yet. If you already know then the event to be insured against effectively already happened. You can't expect to switch to lower deductible fire insurance after your house catches fire but before you file the claim. But equally, if you bought it to begin with the insurance company can't cancel your policy just because you're about to file a claim.

> The price sensitivity is at the wrong end - it should be at the medical provider end, not at the insurance end.

How is that supposed to help? The medical providers are the ones who profit from over-providing. They have no incentive to eliminate unnecessary costs -- to them the costs are profits.

> Why do you think the cost for treatment is low when you're covered under medicare (for low income people)? It's because medicare is such a large buyer that hospitals are able to sell their services at that low a price.

It's because Medicare pays below amortized cost and relies on private insurance to pay higher prices and cover the providers' fixed costs. That doesn't exactly work if you get rid of private insurance.

> no it's not price control.

So let's think about this. There is one buyer. If they won't buy from you, their own customers have no alternatives, so you can't make the case that they need to buy from you or their customers will switch to their competitor who does. If they won't buy from you, you have no buyers.

The buyer can set any price they want and the provider has to take it or go out of business. That's price controls.

> Insurance companies currently all own their own little monopoly in their region/network, and hence, there's no competition for pricing the medical treatment today. You are forced into the insurance's monopoly (or face the higher ticket price hospitals charge because they can).

The existing system is all messed up, nobody is denying that. But why not fix it? Require price transparency. Stop creating tax incentives for low deductible plans that make it so nobody has the incentive to shop around and then consequently nothing is configured to enable anyone to do that because nobody does.

> Insurance companies provide efficiency in operation vs gov't perhaps - i don't know. But what efficiency they provide is taken out as profit instead of being passed on to customers.

Not in a competitive market it isn't. If insurance companies were making above-market returns then it would be profitable for rich investors to start a new insurance company that takes their customers by charging lower insurance premiums and still makes at least the market rate of return, until such time as the efficiency is getting passed on to the customers.

> And insurance company's efficiency is not in lowering the cost of medical care - it's in finding customers that don't cost them more than premiums they charge.

Neither of those is true. If an insurance company can deny a claim for a legitimate reason then it saves them money, which in a competitive market is passed on to the customers.

And insurance companies can profit by identifying higher risk customers and charging them higher premiums. The insurance company's job isn't to avoid risk, it's to accurately price it.

Meanwhile the real efficiency doesn't come from the insurance company at all, it's from not using insurance for low cost routine care, which makes the patient price sensitive. Then the patient has the incentive to choose the provider with the better price and is inclined to refuse procedures that are unnecessary or not cost effective.
