However in Europe you've been warned. In the US we walked (or sat?) way too far down this path before discovering how bad it is. Now that we all know better, you can change your path before getting where we are.
OTOH, my wife are generally stupified looking at twenty-somethings smoking. Our parents didn't know better, and in fact during WWII the Army included cigarettes with meal rations. During our generation (I'm a later Boomer.) we sort-of knew better, but the cigarette companies didn't actually admit they were lying until well into my adulthood. For this generation there's no doubt about how bad cigarettes are, but if anything smoking seems to be on the rise.
I wonder if Hari Seldon would have said that masses of people are stupid, as well as predictable.
