Or... it is a tale told by an idiot, full of sound and fury, signifying nothing. Not a Trump fan, but if Sanders gets the nod the attack ads will practically write themselves. Almost anybody who doesn't live next to a major body of water is either not going to vote, or hold their nose and vote for Trump.
If Sanders were to get elected, there is no way 90% of this, especially the energy sector stuff, gets enacted in the US. Even if both houses of congress flip, between Senate filibuster rules and red state dems, stuff like the transfer of energy sector production to the federal government isn't going to happen. What is more likely to happen is utter gridlock, and the environmental problems will only worsen.
As far as "but there's jobs" argument, if I'm reading TFS correctly, we'll spend $16 trillion to get 20 million jobs. If my pre-beer math is correct, that's $800k we'll be spending per job. There are other benefits to be costed out, like lower spending because people aren't breathing fumes/particulates, maybe lower military costs because we'll be less invested in securing oil drilling/transport in hostile parts of the world, but those seem difficult to predict objectively. There might be some additional money coming in from lawsuits, assuming Sanders can get the judiciary to play along, which seems like a stretch with the Supreme Court being what it is.
Still think the best thing here is to let things play out, and have humanity end itself before it can infect the rest of the cosmos...
