Earlier quoted context omitted.
Yeah, but that smoker would have paid a lot more in tobacco taxes and won’t be collecting a pension.
I suppose there's even environmental benefits to smoking/drinking yourself into an early grave. Think of all the resources you won't consume and CO2 you won't emit by not living those extra years
What they found was that smokers, on average, died early so they collected a decade or two less in pension payments. They paid tens of thousands in tobacco taxes. And when they did die, it was relatively quick and not that expensive to treat (chemotherapy). Overall, smokers were a net benefit to society.
That equation might have changed today with expensive lung cancer drugs and longer life.
