Millennial here. You are completely right. You were born in a world and a system where you are constantly told everything is all right if you just work and consume and yet everything is falling apart and we are destroying our world and ourselves doing so while the "rewards" seem to be further away and feel more shallow than ever. It does not make sense and it's perfectly understandable to get apathetic over it. I only wish you would get more angry about it and less indifferent, but at the same I see that there is already way too much anger in the world and people are already constantly screaming at each other. Also, we didn't do enough either and failed to bring much substantial change. Gen Z ist right in the way they feel. You are not lazy or unambiguous or "lacking drive" or whatever. And it's also not the internet or smartphones or games or anime or whatever. It's a society headed to its doom by living a lie that's rotten to the core and the carrot you are supposed to chase starts to smell foul.
