Seems a bit harsh. Playing video games has no particular ROI (unless you want to go into creative arguments), but they cost money and take up time. Fulfillment, joy, wisdom, those are valuable even if you can't exchange them for cash.

The issue is probably rather the insane costs of education in some countries. If I had to go into debt for a big chunk of my life to study, I'm not sure I would have done it without a clear path towards paying that off.
