First and most important, the Church will not accept any legislation that mandates coverage, public or private, for abortion, euthanasia, or embryonic stem-cell research.
We refuse to allow our own parish, school, and diocesan health insurance plans to be forced to include these evils. As a corollary of this, we insist equally on adequate protection of individual rights of conscience for patients and health care providers not to be made complicit in these evils. A so-called reform that imposes these evils on us would be far worse than keeping the health care system we now have.
Second, the Catholic Church does not teach that “health care” as such, without distinction, is a natural right.
The “natural right” of health care is the divine bounty of food, water, and air without which all of us quickly die. This bounty comes from God directly. None of us own it, and none of us can morally withhold it from others. The remainder of health care is a political, not a natural, right, because it comes from our human efforts, creativity, and compassion.
As a political right, health care should be apportioned according to need, not ability to pay or to benefit from the care. We reject the rationing of care. Those who are sickest should get the most care, regardless of age, status, or wealth. But how to do this is not self-evident. The decisions that we must collectively make about how to administer health care therefore fall under “prudential judgment.”
Third, in that category of prudential judgment, the Catholic Church does not teach that government should directly provide health care.
Unlike a prudential concern like national defense, for which government monopolization is objectively good – it both limits violence overall and prevents the obvious abuses to which private armies are susceptible – health care should not be subject to federal monopolization.
Preserving patient choice (through a flourishing private sector) is the only way to prevent a health care monopoly from denying care arbitrarily, as we learned from HMOs in the recent past. While a government monopoly would not be motivated by profit, it would be motivated by such bureaucratic standards as quotas and defined “best procedures,” which are equally beyond the influence of most citizens. The proper role of the government is to regulate the private sector, in order to foster healthy competition and to curtail abuses. Therefore any legislation that undermines the viability of the private sector is suspect.
Emphasis mine. The bolded parts are excellent illustrations of his point.
