You're arguing that the problem with Donald Trump is that he's too green and/or too into creative destruction, and will cause the oil industry to implode?
Hm.
No, I think the implication is that if oil workers lose their jobs, while Trump promises to "make oil great again" (he's certainly threatened to cut funding for green energy), oil workers might vote for Trump.
There is a very high likelihood that this has already happened, and the voting will follow in the next day or so.
I meant only that when the structure of the economy changes to quickly, reactions like Donald Trump occur. If the US had been better about integrating all the people employed by manufacturing into the "new" economy I don't think they'd be so desperate for the kind change they think Donald Trump represents.
