This is Typical

The left was rightly ticked off a while back when the Bush FDA went against the scientific panel's recommendation and refused to approve the Plan B morning after pill for over-the-counter-sales.  But as I discussed here, the typical political response of our two political parties to such abuses of government power is NOT to reduce the government's power, but to try to redirect the abuses for their own ends. 

So, in this case, the left now is not necessarily upset that the FDA is using non-scientific criteria for approving drugs, they are just upset the FDA is not using their pet non-scientific criteria:

Now an interesting article in the Baltimore Sun
suggests that some left-wingers are also hinting that ethical concerns
should be included in FDA regulatory decisions. In a poll last fall,
the Pew Initiative on Food and Agriculture found
"a strong majority (63 percent) of Americans believe government
agencies should include moral and ethical considerations when making
regulatory decisions about cloning and genetically modifying animals,
with 53 percent feeling that way strongly."

Liberal bioethicist, Daniel Callahan, co-founder of the
Hastings Center in Garrison, N.Y., says that he is leery of having the
FDA rule on moral issues, but thinks that it might want to consider the
financial impact of approving new drugs on the health care system.
Presumably, the regulators might decide that a drug is too expensive
and refuse to approve it although it is safe and effective. The problem
is that deciding to withhold a drug from patients because regulators
think it's "too expensive" is a moral judgment. If the government
doesn't want to pay for an expensive drug that's OK, but why should
regulators forbid consumers, who might want to pay for it on their own,
access to drugs that are safe and effective?

Carol Tucker Foreman, director of food policy at the Consumer
Federation of America, points out that the FDA has already taken into
account non-scientific concerns in some of its regulatory system. For
example, she notes that the FDA requires that irradiated food be
labeled even though there is no scientific evidence that irradiation harms human health. The reason for the labels is that activist groups like Public Citizen
managed to scare some consumers into demanding them in the early 1990s.
Now the question is should the FDA be pushed further down this slippery
slope of non-scientific regulation?

The labeling for irradiated foods is stupid but fairly harmless, but the suggestion to hold life-saving drugs off the market if they are deemed too expensive by some bureaucrats is obscene.  I would suggest you run away screaming from anyone who suggests that this is a "moral" decision.
