An eloquent article, Free Lunch 'Safety', by Thomas Sowell.
If a drug is not safe, neither is the illness for which the drug is prescribed. Nor are alternative drugs likely to be perfectly safe, since nothing else is. Life involves weighing alternative risks, whether in football, pharmaceutical drugs, or a thousand other things.
Precisely, this concept of trade-offs is ignored or not understood by lot of people who continuously demand perfection. They don't realize that to achieve their ever increasing demands the costs become too high for many people including the businesses who often times have these demands regulated upon them.
