yeah but u can use all the 98% of knowledge to become a millionaire since you got an awesome job
or u could be homeless
dude you're not listening-
2% of school is useful. meaning you can get a job and live somewhere comfy- doesn't have to be big- and be happy-
sure if you want a big time gig or something like that you could do the extra lessons and stuff to help you but with 2% you're fine-
and not all homeless people didn't learn enough to get a job maybe they were retired and had no money left or they drove all way out here for something but they didn't bring enough money to get more gas.
