There have been multiple threads on this and on each one some posters fail to recognise that their reluctance to 'prop up pret' isn't going to start and end with pret going under. The people who work for pret aren't tax dodging multi millionaires, they're your neighbours, the people you see at the school gates, at the gym.
Yes, in the longer term they might find work in these new suburban cafes filled with people working on their laptops (I wonder how long the cafes will tolerate that without having to impose a minimum spend?) but in the shorter term they're no longer buying the product your company sells, subscribing to extra tv channels, buying luxury goods (and insuring them) and food, signing their kids up to extra curricular activities, booking holidays, going to the pub, buying furniture, using public transport, trying a new hobby. And yes, maybe you aren't a bus driver, or a sky technician, or a kids guitar teacher. But are you an accountant? Do you work in HR? New business development? Contracts? Facilities? Do you think those departments will be unaffected when the company's profits start to slow?
It is likely that we do need a change, and more likely still that it's coming whether we like it or not. And as other posters have stated, it might very well be a good thing long term, but to ignore the short term damage it is going to cause because you think you're insulated from the ripple effects is short sighted. There are, too, the very good points made about new starters, both to a particular job and to working in general, work experience, apprenticeships etc. I'll go further and add friendships/relationships, which for a lot of people is something that develops in their first few roles in particular.
I also suspect that a year from now, some companies will not be prepared to accept the hybrid wfh/childcare situation that they are forced to accept now.
