I think this is immaturity and entitlement and has always existed in the younger generations before reality beats it out of them, I think the main difference between now and the past is simply that social media allows these people to connect and egg on each other more than in the past.

What will happen is a few of them will go too far on TikTok, the nail that sticks out gets hammered down and the rest will withdraw from the platform. Those that grow up and mature will be successful, those that don't will forever be annoying kids wondering why their life is shit and never taking the responsibility or the agency to realize that it's in their power to make it not shit. They'll become the asshole bosses they despise now and still complain about those above them being assholes.
