Pharmaceutical companies have every incentive to make their drugs safe, because if their drugs hurt people, the drugs will not sell.

Many drugs have passed FDA approval but later killed people. If the FDA were a private company, it might have gone out of business. But as a government monopoly, it's very hard to stop paying for. Between pharma companies, the government, and individual patients, the FDA has the least stake in the health of a particular patient.

UL is an example of a non-government organization that offers product safety certification. You see the UL seal on most consumer electric appliances. Imagine an FDA seal.

Drugs are not magical or special. They are a product like any other, and it is the consumer's right to choose a doctor, and for that doctor to choose proper medication. We regularly choose the best mechanics, plumbers, and other specialists we can find, and their reputation is partly a function of the type and quality of the parts and tools they use.
