"Externalities have been a part of economics for years"
Okay, why hasn't a carbon tax, the most basic example of an applied cost externality been applied yet? 1 gallon of combusted gasoline is 20 pounds of carbon dioxide. It costs about 100$ to sequester a ton of CO2.
It is chemistry 101.
Show me you can do the math. At a MINIMUM for the offset of JUST THAT GALLON OF GAS, how much should the carbon tax be?
"I've had it with your irrelevant sanctimonious rant"
Okay, bury your head in sand, professor. It's not your fault. It's not the fault of your, ah, "field of study", you guys were just publishing papers about meaningless game theory and "ideal conditions" equations that had no applicability to the real world.
A bunch of right wing zealots took your little brain teasers and overapplied them to the world to justify their positions. Milton Friedman got a little full of himself and overstepped his bounds and had fun yukking it up with the fat cats. Your central bankers just throw darts at the wall, print some fiat currency, and cross their fingers, and enjoy a nice pension.
Keep handing out your "in memory of Alfred B. Nobel" prizes.
Meanwhile, real science and technology marches on, and actually improves people's lives.
