An example of an increasingly popular trend that conflates what I'd call "value nihilism" with "action/effort nihilism". There's a huge difference. Value-nihilism is kind of soul-sickness that's probably super rare in the general population and usually comorbid with stuff like dark triad or clinical depression. Action/effort nihilism, or the POV that nothing can be done to improve things, is just realism or pragmatism in a party mask.
Value-nihilism cannot be disproved or even argued with, because there's no place to stand. On the bright side(?), action/effort nihilism is a pretty simple thing to cure if you're in a leadership position. Reward effort, intentions, results, and keep the promises you make so that people can plan for their future and have agency. Stop playing corrupt and counterproductive games with politics, optics, nepotism
