Lately, activists have become obsessed with "conflict of interest" in science—any trace of corporate money must poison honest medical research. Obamacare includes a rule called the Physician Payment Sunshine Act, which orders companies that make medical products to disclose even bagels they serve doctors and anything valued above $10.
But rules like these only make life more difficult for doctors, and for patients who want cures, argues John Stossel. Markets do not automatically taint science. As with every other service the market provides, it is the anti-capitalist attitude that does more harm.
