For sixth formers and students they have in many cases lost a lot of once in a lifetime/rite of passage experiences that they won't get back. I might have had to spend time at home and missed out on a number of holidays and parties I'd been looking forward to but there'll be other opportunities for those - not so leaving school/graduation etc.
@Londonmummy66: you're forgetting that they won't know any different. Shame on any parents who try to project their own youth experiences onto their children who are no doubt much more resilient and coping perfectly fine without a shirt-signing last day at school, or a boring graduation ceremony. I can't even remember my last day at school, and I only went to my graduation ceremony to please my parents- it's just a thing that you have to sit through for many many people.
Yes, I feel sorry for young people, but not for these trivial little things that you mention. I worry that their university teaching will not be value for money, that they will not be able to use their student accommodation for half the year despite paying for it, that the part time job they were relying on to get them through financially won't be there anymore, that they will be stuck in a minimum wage job when they graduate and their uni experience will be a total waste of money....
