People needing to work so hard is intentional. I remember growing up, and watching technology boom, and thinking we're gonna have to figure out something soon, because fewer and fewer jobs will need to exist, and yet more people are working more jobs.
Society has encouraged people to not make friends, making being a loner and hyper introversion cool. They want people to work 12 hours, go home and watch TV, and have no energy to do anything else. Convince people that it is a choice or personality quirk or feel alone all the time. When really you just never have any time to recover your social battery, because you're always working.
They're trying to convince us that it's the generation, it's not, there were always introverts. They just know if people have time to get together, they have time to organize, they have time to think about why it's like this. They have time to realize they aren't alone.
