Schools exist for the same reason that farms and factories exist: it's a lot more efficient having specialised workers (in this case teachers) who can do the job far more effectively (in this case teach 30 or so children) than having every person do it themselves (in this case every parent take a large portion of time out of their day to teach their own child individually).

The alternative to school was for girls to help out around the house until they were married off and for boys to either learn their father's trade and then do that for the rest of their lives or get apprenticed off to whoever could take them and then do _that_ for the rest of their lives.

School helps children create a life for themselves. If children don't learn anything there they'll find far fewer paths open to them later on.
