To expand a bit, what is going to prevent your new "stronger" government from getting captured by the very same lobbyists, except now they'll have even more power to distort and manipulate the market?
In this specific case, the fundamental problem appears to be that only one company has jumped through the FDA hoops (which can cost billions) to sell "prescription" niacin. How is piling even more regulation on top of that going to make the problem go away?
