Under liberal capitalism, how you feel about the state of the world/economy is going to always be tied to how much money you're bringing in every month, so making a comment about how things are actually fine and Gen Z are "negative" and ungrateful is pointless if you're not going to make clear your own economic standing relative to others. I would be surprised if you're delivering Uber Eats with a Bachelor's degree, as many of Gen Z are doing today, considering the sentiment expressed.
