She's not complaining or asking to be handheld. She's warning her fellow students that working to make money will impact the ability to pay for school.

It's counter intuitive. It's not obvious at all. It's barely mentioned or talked about. It can cost (and it did cost her) a college degree.

I don't disagree with the sentiment of your remark, but it's completely out of place here. She's simply warning others not to do the same mistake, since it's an easy one to make.
