"A full accounting shows that government programs cost more and deliver lower-quality care than private insurance. The central problem with proposals to create a new government program, however, is not that government is less efficient than private insurers, but that government can hide its inefficiencies and draw consumers away from private insurance, despite offering an inferior product.
A health insurance 'exchange,' where consumers choose between private health plans with artificially high premiums and a government program with artificially low premiums, would not increase competition. Instead, it would reduce competition by driving lower-cost private health plans out of business.
President Obama's vision of a health insurance exchange is not a market, but a prelude to a government takeover of the health care sector. In the process, millions of Americans would be ousted from their existing health plans."
