That sounds like underlying malevolence and sociopaths making excuses to try to duck responsibility which get accepted and perperuated. So very not new - forba close to modern example see the Irish potato famine and how Malthusianism was used to excuse exporting food for short term profit and leaving them to starve because "their population was unsutainable". Since someone who opens fire on a crowded highway to "reduce future traffic" is still a callous psychopath.

The solution then is accountability to those in power - for negligence. Treat the snake oil salesmen who sell racism in a box like the sociopaths who sold dowsing rod bomb detectors for both have shown a callous disregard for human life in pursuit of profit. This isn't radical - not doing it is radical and messed up.
