After not knowing the important stuff that's the only option you have

yes it is to teach you, give you knowledge and study for jobs. (also why would we choose a 5-9 hour shift at McDonald's?)

So you're telling me you go to school just to get some shitty 5-9 hour shift at McDonald's just to get a bit of money and struggle with same things as other people just because they can't get money? If you wanna get a job at least be an accountant because yes school teaches you stuff but it doesn't teach a LOT about stuff like jobs taxes money Investment or anything like that, they just teach you "study and get a job" but yes keep going in school 💪🏾
