It seems that Yarvin didn't realise -- accidentally or more probably intentionally -- that the society in Soylent Green was not supposed to be taken as a model to emulate. It's not supposed to be a documentary! To even joke about it is telling.

As a tech industry we'll probably be complacent on whatever is coming up in the future, no matter if it's something like this or something far more insidious. But hey, some of our class got very wealthy and got to enjoy material prosperity so it's all good, right? People would chase ever higher wages and shiny trinkets and end up working for Evil Megacorps because "one needs to be able to afford to live comfortably".
