Yes. I agree. However, when industry gives 0 shits for external costs because they can 'get away with it' then I can see taking a hardline approach. E.g. Berni

Yes. I agree. However, when industry gives 0 shits for external costs because they can 'get away with it' then I can see taking a hardline approach. E.g. Bernie is essentially saying: "Hey you guys screwed up, you polluted the environment, tried to hide this fact by funding shoddy research. You could have been adults at the table by acting on the early reports or done better on the cleanup, but you didn't do the right thing. So we the people need to punish you, and there is no better way than by taking away your toys." It's a hardline stance, but hell if your tap water became flammable you might feel the above is perfectly reasonable. Now add this across the nation with all the other examples of large entities unfairly getting away with it and we can all understand why Trump/Sanders are popular.
