The problem with health care costs is the insurance

The Democrats' health insurance reform proposals will magnify the problems that make health care so expensive:

The administration's plan will impose mandates that employers provide coverage, mandates that individuals obtain coverage, and mandates about the form this coverage will have to take. These will remove the freedom to choose one's health-insurance plan, because government, in its effort to correct perceived inequities, will dictate which health-care services must be covered and which health-care providers must be used. ...

The mandates will lead to large increases in the cost of health insurance for everyone. Research studies have shown that as people become insured, especially under a health plan that offers broad coverage and low copayments, they consume more health-care services. The best estimates indicate that each newly insured person will approximately double his or her health spending.

With 30 million to 40 million newly insured persons under the administration's plan, aggregate health-care demand will increase significantly. But when demand expands prices increase. ...

The mandates will also have adverse additional longer-run consequences. According to provisions in both House and Senate bills, mandated plans must have low copayments and provide coverage of health-care services that is at least equal in scope to a typical, current employer-sponsored plan. But these are the very flaws that are responsible for high and rising health-care costs...

Comprehensive, low-deductible, low-copayment insurance has brought us to where we are today. The administration's plan to expand and lock-in this flawed paradigm will ultimately defeat the goal of making health services more affordable for everyone.

Again, insurance is what causes health care to be so expensive, because it encourages the population as a whole to purchase more health care services than it otherwise would. Increased demand then pushes up prices. As I quoted economist Martin Feldstein in an earlier blog post:

Since a typical 20% copayment rate means that an extra dollar of health services costs the patient only 20 cents at the time of care, patients and their doctors opt for excessive tests and other inappropriately expensive forms of care.

By the way, here's a list of reform ideas that the Democrats are ignoring. Here's a functioning national health care system that results in far lower costs than the European-style health care systems that the Democrats want to emulate.
