Some analysts have predicted for some time that the city centre as a shopping destination has had its day
It is constantly changing, of course. At one time small individual shops were the norm, along with markets which supplied food and essential goods. Those who were more entrepreneurial flourished eg Mr Marks and Mr Spencer who together opened stores "Admission Free", as well as market stalls; consequently came the demise of the local drapers' shops.
Sainsburys, Tesco (Mr Cohen started with one stall), Woolworths, British Home Stores, Debenhams etc etc all dominated the High Street.
Gradually smaller retailers were forced out.
Then came the large shopping malls where large stores relocated leaving High Streets with gaps to fill - banks, building societies, charity shops, coffee shops and niche retailers began to take over.
Now we are not really allowed to shop because we risk spreading COVID so only those who can adapt will survive, possibly niche retailers better than the large department stores and chains.
That is the key - adapting to changing circumstances over the years. Those who cannot for whatever reason will close.
We are not supposed to shop, in most areas the shops are closed except for essential goods so we shop online for our needs.
A reset will be needed post-Covid.
