While I disagree with Sadolite because I'm a very socialised-education type of person politically and wish loans almost didn't exist (but the social democracies that have loans actually make you pay it back very, very slowly in a reasonable way), I agree with the notion that if we are to run schools as a preparation for working in the Capitalist business-centric world, we are not supposed to teach children the arts.
I do not agree that sports should be removed and I am saying this as the type of dude who was not athletic and was picked near-last for teams in group vs group scenarios. I'm just saying that sports are undeniably better and more necessary than the arts if we are talking about what children need to learn and do at school regardless of their upbringing and home life. Arts are unfair regardless of the passion one feels inside because you may love acting, singing, painting, instruments etc but your genre and/or style is not suited at all to the strict curriculum. Arts can't be sufficiently taught as an educational regimented thing in schools but they can be flexibly taught in specialised university classes and perhaps for 16-18 year-olds they should be made available but not for 14-16 or younger to any significant degree. There should instead be a period in the day called 'structural recreation' where artistic pupils are free to go to a free-form acting thing run as a club and a lot of extra-curriciular activities that are relatively free or cheap for students to partake in should be available in any school, public or not. This is very important because it allows the people drawn to the arts to engage in the arts and those who aren't drawn to it to not be forced to waste time doing them. Sports help health for any student. There is no student who sports are bad for but there are some special needs that will make it more complex to provide sports for students, just as with any subject vs special needs students.
