That's been the lowbrow sales-pitch for insurance since the first policy was sold. But it's a come-on and we've finally got all the evidence we need to realize that in the long run, it doesn't work that way. Insurance adds unnecessary overhead to every transaction it 'covers'. Insurance is a gamble, and in the end the house always wins.
Insurance makes sense as a way to hedge your bets; to 'cover' unlikely losses that would bankrupt you outright. As a means of paying for day-to-day health care expenses it's irrational and poisonous to the health care market.
You apparently consider routine healthcare a yearly checkup and an occasional prescription. That may be true for some but not for many millions. My wife has three prescription that she must take or she'll be in the hospital. The cost is over $800/mo. plus office visits and tests. Her total medical cost are over $15,000 a year and she's not even sick. These are routine costs and are enough to bankrupt a lot of families if they don't have some type of insurance coverage.
Most of what you call routine costs goes to the treatment of chronic diseases such as asthma, diabetes, heart disease, COPD, and arthritis.
More than 75% of health care costs are due to chronic conditions. About 133 million Americans, nearly 1 in 2 adults live with at least one chronic illness. Routine treatment often runs in the thousands of dollars/yr.
We are approaching a point where health insurance,either private or government is not an option. For many millions it's the difference between being able to lead a productive life and not living at all.
Think about that. If you'll allow the paraphrase, it sounds like you're saying that health care has become so expensive that only the insured (and the very rich) can afford it. I'd have to agree that's case. And it's getting worse.
But what do you think would happen to the prices for those drugs and services if suddenly far fewer of them were covered by insurance? If
most of us were paying out of pocket for
most of our health care, and relying on insurance only for catastrophic coverage, prices would fall dramatically. It would also increase demand for cost effective alternative treatments and more efficient delivery systems - something we now have to coax out of providers with ad-hoc "incentives".
As counter-intuitive as it might seem, I'm convinced that the only way to fix the health care market is to minimize and reverse the damage done to it by our abuse of insurance. And the first step in doing that is to remove all the incentives for over-insuring built into current legislation. (i.e. stop making things worse).
Unfortunately, we're moving in the opposite direction. I don't know whether our leaders don't understand this, or don't care. (The third option, that I'm just wrong, isn't currently under consideration.

)
I know that many progressives support PPACA, even though they admit it won't do much good,
because of the harm it will do to the health care market. But I think they're misguided in their assumption that destroying the health care market will bring about socialized medicine. As PPACA has shown, our leaders want corporatism, not socialism - and that's what we're doing to get.
