Many of my students have a job starting age 16. Many save for a car, many save for buying nice clothes that parents wouldn’t buy them, many buy electronics etc They work in stores or restaurants or other random local stuff . ALL have disabilities of all kind of varieties including cognitive impairment.

If you were accepted to university you certainly have intellectual ability to hold a job, at least part time while in school. Why aren’t you working? The only way to be able to afford things is to work. How else would you be able to get all those nice things you want?
