Why is it hard for normal consumers to force the FDA to do what is best for them of prescription drugs?

FDA (Employees of the Food and Drug Administration) makes decisions whether the new medicines or prescription drugs can be available for the public or not in the United States. It is impossible for physicians in America to prescribe the medicine or drug when FDA does not allow it.

All drugs take time to make sure its benefit for patients and prevent the life-threatening. There are two conditions that the new drug would not be introduced: unsafety and ineffectiveness. Type 1 error - the thalidomide possibility and the type 2 error - the introduction of drug is delayed (drug lag). From this point, the type 1 error is visible but type 2 error is hard for those who do not have professional knowledge to identify.  

In order to realize and prevent Type 2 error, it would be required for consumers to have professional knowledge in medical fields, especially medicine. Without the ability to examine the benefit and side effects, it would be hard for consumers to force FDA, insisting to break down the drug lag. From these reasons, consumers cannot simply force FDA to do what the best for consumers of drugs is.
