If these people had a job or at the very least a constructive hobby they simply wouldn't have time to dedicate all their energy into sperging about how WORK BAD REE.
Ever since the dawn of Man, everyone was busy, there was a struggle, a natural struggle for survival. To put it bluntly, if you didn't hunt, you didn't eat
Fast forward to the present day and all your basic needs are taken care of without you even having to lift a finger. You have a roof over your head, with heating and luxuries. Hot food made with minimal effort (most of these people eat out more times a month than I do in a year and if not that, they just throw everything into a microwave). I'd imagine these people live off some sort of government handout if they've even moved out of their parent's house at all.
There is no struggle, there is no stress, there is no need to fight, there is no need to focus your energy into anything at all.
Humans haven't evolved to live like that and we probably never will. We need some sort of struggle or purpose to keep our minds satiated.
In this state of sheer convenience and comfort your belly might be full at all times but your body is getting ever fatter and your mind ever duller.
So the solution? Resorting to making up a struggle, making up something to worry about, in this case it's "Ugh! Why should we work? That's like... Slavery bro!"
You can more or less apply this to most reddit/tumblr tier worries and first world problems. From becoming a fucking multi gendered demiqueer faglord to unironically LARPing as a communist. These people are so taken care of they revert back into a state of infantile screeching.
And for the few among them that actually have a job, it's probably their first. It's likely they just got out of college with a degree in God knows what with minimal life experience and even less connections. Baby's first job is rarely something you're over the moon about, but putting the least amount of effort in just to get by rewards you with some pay at the end of the month, no?
They just don't realize that life isn't a fucking Animal Crossing simulator, it's more grindy than that. But they'll waste any potential they have in sperging over things they consider an issue. Not one of them has a solution that isn't "just tax the rich and like... Give everyone free money, bro!"
