but more people working in delivery - it all evens out in the end except it doesn’t, you provide far more jobs from an actual store, even down to the cleaners, the window washers etc than you on with an Internet business. Advertising and marketing will also die as an industry, it just becomes data analysis to target ads. Delivery drivers are also paid very poorly. I think we should be considerably worried. I don’t actually think the high street would have disappeared thanks to online shopping, rents, parking charges etc have all sped things up, and now masks.
It's not just delivery drivers - there's a whole industry around the vehicles - manufacture, sales, design, repairs, maintenance, etc. One of my clients is a "one man" garage and he's never been busier with doing tyres/brakes, servicing etc for courier drivers. If you include peripheral jobs such as cleaners then surely you have to also include mechanics, vehicle salesmen, etc don't you?
As for the High Street - it's been dying for years, if not decades. It's high street "identikit" chain stores that have been slowing killing it. Dozens of chains went to the wall long before Covid - even back in the noughties, big names were disappearing. The rot set in back in the 80s/90s when independent stores were forced out by the identikit chains - that also led to ridiculously high rentals demanded by the landlords (again, no longer privately owned but now mostly owned by pension schemes, private equity funds, etc - sometimes the same consortia of rich (often overseas) financiers who own the chain stores.
Don't forget that before the 80s, the High St wasn't even dominated by retail. Most town centres also had factories, warehouses, breweries, print works, doctors, dentists, offices, etc on their High Streets. Much of that was demolished/converted for identikit High street chains, private equity backed shopping malls, etc. I'd argue it was never sustainable in the first place. Shopping malls, chain stores etc seem to have a history of regular change of ownership, massive losses, etc.
We need to be realistic and start re-modelling town centres away from the retail model and re-purpose them back into where people live and work, not just where people go to shop.
Covid has accelerated the decline of High St chain stores, not caused that decline.
