Mostly by preventing lifesaving drugs and devices from ever being brought to market through their insane trials structure. The FDA's response is basically "We're extracting rent, shove off":
Like much in life, I guess it all comes down to money. And FDA explains that they don’t have any extra. Congress has been underfunding FDA for decades, and the agency only stays afloat now by virtue of user fees the industry pays to get submissions reviewed. The FDA flat out says they do not have the money to undertake the work that would be involved in creating new classifications.
Mind you this is omitting the bad drugs like Lipitor they let through due to bribery.
