Private health insurance today fails to achieve these goals. It is also the primary cause of the rapid rise of health-care costs. Because employer payments for health insurance are tax-deductible for employers but not taxed to the employee, current tax rules encourage most employees to want their compensation to include the very comprehensive "first dollar" insurance that pushes up health-care spending.
A good system should not try to pay all health-care bills. That would lead to excessive demand, wasteful use of expensive technology and, inevitably, rationing in which health-care decisions are taken away from patients and their physicians. Countries that provide health care to all are forced to deny some treatments and diagnostic tests that most Americans have come to expect.
Here's a better alternative. Let's scrap the $220 billion annual health insurance tax subsidy, which is often used to buy the wrong kind of insurance, and use those budget dollars to provide insurance that protects American families from health costs that exceed 15 percent of their income.
Specifically, the government would give each individual or family a voucher that would permit taxpayers to buy a policy from a private insurer that would pay all allowable health costs in excess of 15 percent of the family's income. A typical American family with income of $50,000 would be eligible for a voucher worth about $3,500, the actuarial cost of a policy that would pay all of that family's health bills in excess of $7,500 a year.
The family could give this $3,500 voucher to any insurance company or health maintenance organization, including the provider of the individual's current employer-based insurance plan. Some families would choose the simple option of paying out of pocket for the care up to that 15 percent threshold. Others would want to reduce the maximum potential out-of-pocket cost to less than 15 percent of income and would pay a premium to the insurance company to expand their coverage. Some families might want to use the voucher to pay for membership in a health maintenance organization. Each option would provide a discipline on demand that would help to limit the rise in health-care costs.
