The poly marriage I'll give you
Hah, that's actually kinda ironic, since that was the least of my examples, and Heinlein Did It First(?) back in the 60s (in
The Moon Is A Harsh Mistress — possibly also
Job, don't remember for sure), as did Samuel R. Delaney later on (
Driftglass, in the same-named collection of short stories). Delaney even included/implied queer couplings in his poly-marriage model (whereas Heinlein's was unabashedly het, IIRC). But back in the 60s, SF was still fairly fringe (AFAIK); very few 'respectable'/ mainstream publishers wanted to have anything much to do with the genre.
but the rest I don't really think is millenial specific.
Well, while global megacorps have been an SF-staple since cyberpunk (early 80s) at least, up until the late 90s they were still generally portrayed as 'good' to 'neutral' (despite profit-driven), rather than
actively malevolent, à la Mao-Kwikowski.
PMCs are also a pretty new thing, AFAIK (
@Commodore would probably know for sure). Certainly, the War on Terror (Afghanistan invaded in 2001) and Gulf War II (Iraq invaded in 2003) was the first time
I became aware that they existed. I mean sure, mercenaries have been employed in force since at least the Romans, but AFAIK, modern, organised merc companies had never previously been officially sanctioned/approved by any government before Dubbya+Cheney employed Blackwater.
Resource wars likewise. While us Civ-players have known since at least 1991 that
all wars are essentially resource-wars (even if that 'resource' is only territory), it wasn't really until the late 90s/early 00s (again, with Bush Jr declaring the WoT) that this concept seems to have filtered out into the mainstream.
Increasingly vast wealth disparity as a result of capitalism was predicted by Marx back in the late 1800s, sure, but it's only since the GFC in 2008 that it's been an increasing preoccupation, and of millennials specifically — you've posted lots of examples yourself...
And although Orwell warned us all to be on our guard back in 1948, informational oversight to the degree possible today, was only
made so by the widespread use of the Internet, i.e. again, not until the late 90s/early 00s.
Environmental collapse has been threatened in SF for decades, but up until the 80s the trigger-event tended to be either nukular war or an alien invasion. Again, it's only relatively recently that humans in general (i.e. beyond the hippie-fringe) have started tentatively admitting that maybe, juuuuust
maybe, it might have something to do with our industrial/consumerist activities (and there's still plenty who
don't think that, or think that even if, then God will sort it all out for us...)
Your honour, the defence rests
