Can someone eli5 why this is a good thing in an aging economy already struggling to meet pension demands.

Not trying to be saucy I just don't get it.

Edit: nevermind I missed a important part of the article, it's in response to universities profiteering off of international students with exorbitant rates specific the them, makes sense.

However I have to question if oversight and punishment of universities profiteering with less than stellar academic outcomes would be more effective than capping intentional student enrollment. Doesn't sound like it directly addresses the issue.
