Well, we need both and we should keep exploring both, although we can probably get away from gas sooner.
Norway is actually a great example of what I think we should do: keep using oil in order to fund a rapid transition to green power. It's working well for them!
The government is investing record amounts in green energy, approving record numbers of green projects and rewriting planning law so it can approve even more.
The problem with 'cracking down' on benefits is identical with the problem of 'cracking down' on immigration. These things are just not real problems and the people who think they are problems are flat wrong. You can't do anything about unreal problems, because the people who believe in the fake problems just don't believe in reality.
The Marxists Internet Archive has a huge amount of left/communist non-fiction. It's very broad in its scope, so there's Stalin and Mao on there alongside William Morris and HG Wells. You could also check out Timothy Snyder and Rebecca Solnit, who both had interesting books about resisting fascism from a more contemporary viewpoint.
In fiction, there's The Man in the High Castle, by Phillip K. Dick, which has a similar alt history concept as Roth's The Plot Against America. And of course there's George Orwell's writing, both fiction and non-fiction, much of which explores the nature of fascism. I'd also recommend Isabel Allende's The House of the Spirits, if you like magical realism.
I don't know, we already have open source 3D printers and they really haven't brought about the industrial revolution some people hoped. Not quite the same as replicators, granted!
I agree, that logic has been used to justify atrocities throughout history, including right now. It's exactly what Israel says about Palestine, China about the Uyghurs, Trump about Mexican immigrants. And it's completely antithetical to Star Trek's values.
Funny side story is that some Nazis and other German nationalists thought it wasn't 'German' enough, so the leading Nazis felt they had to invent an older 'Germanic' tradition to justify its usage. So, it's a fake German tradition that was in fact borrowed from the Italians, who got it from a fake Roman tradition that was actually made up by a French guy.
My line of argument does not require that the oil be used here.
