I'd wager that no one ruling out the idea that young employees can learn and be trained remotely has ever actually been a young person doing this.
Well, I was a young person who trained to be an accountant by close mentoring/supervision in an office some 40 years ago. Over the past 30+ years, I've been the one mentoring/training school, college and Uni leavers to become an accountant.
I've done a huge amount of working online for the past 20 years. My practice is in the North West and I had clients, 20 years ago, living in the South East and some living abroad, who I never met, so I'm not afraid of online communication and was using Skype etc from virtually the moment it appeared, now using Teams, Zoom and probably all the other popular online "meeting" tools.
I've taught clients how to use book-keeping software remotely. It's a pain in the arse as it takes so long, even when you've got the system set up so you can see the others' computer screen and what keys they're pressing etc. It's far quicker and easier to teach a client how to do book-keeping if they're sat next to you. I do it remotely because if a client is a couple of hundred miles away, it has to be done, not because it's better or quicker (it isn't!).
My current trainee is being taught face to face. My next trainee will be taught face to face. You can't teach someone how to be an accountant over Zoom. Well you can, but it would take a lot more time and be far more inefficient for both parties. You can't beat sitting at the next desk to deal with queries etc that come, literally every few minutes from a trainee, looking at their screen, looking at the piece of paper they're holding, etc.
I'm sure some jobs can be taught by zoom, but not the work of an entire profession. Small bits/chunks of work, yes, remote is fine, but not when it's so much to teach that it's a few hours per day, week after week, month after month! The person "teaching" would never get their own job done!
