Critics say the public option is really a Trojan horse for a government takeover of all of health insurance. But nothing could be further from the truth. It’s an option. No one has to choose it. Individuals and families will merely be invited to compare costs and outcomes. Presumably they will choose the public plan only if it offers them and their families the best deal — more and better health care for less. Critics complain that a public plan has an inherent advantage over private plans because the public won’t have to show profits. But plenty of private plans are already not-for-profit. And if nonprofit plans can offer high-quality health care more cheaply than for-profit plans, why should for-profit plans be coddled? The public plan would merely force profit-making private plans to take whatever steps were necessary to become more competitive. Once again, that’s a plus. Critics charge that the public plan will be subsidized by the government. Here they have their facts wrong. Under every plan that’s being discussed on Capitol Hill, subsidies go to individuals and families who need them in order to afford health care, not to a public plan. Individuals and families use the subsidies to shop for the best care they can find. They’re free to choose the public plan, but that’s only one option. They could take their subsidy and buy a private plan just as easily. Legislation should also make crystal clear that the public plan, for its part, may not dip into general revenues to cover its costs. It must pay for itself. And any government entity that oversees the health-insurance pool or acts as referee in setting ground rules for all plans must not favor the public plan.
