As an adult who got nothing from school, drifted into jobs I didn't like, and eventually started a degree (long boring story) to try and get a better job, ROI is extremely important. I wanted a better life for me and my family. As the father of a child about to head to university ROI for them is extremely important to me. ROI for my child however is not even a consideration because they want to do what they want to do and what do I know anyway, they already know everything. I hope they've chosen something that's useful though! I also would have preferred a full list of courses to avoid if ROI was important.
