We have checked to see if they are addressing the problem more than probably any drug in history. The idea that we haven't is the result of skeptics cherry picking results that back up their point while ignoring the huge quantities of evidence supporting the efficacy of statins and other LDL lowering medications like ezetimibe, pcks9 inhibitors, etc.

Statins are so good at what they do they even reduce the risk in people who are already at low risk for heart disease.
