IMO, one of the problems with the high street is the emphasis on retail (Mary Portas influence?). Whereas in my youth a high street offered so much more: dentists, doctors, cafes and pubs, shoe menders, bike menders, small appliance menders, stationers and printers, newsagents. A great mix of service providers (and retail of course: bakers, butchers, clothing, homewares). All now driven out by high rents and business rates. If councils could encourage a return to that mix, with more 21st century amenities like drop in centres for the elderly, mother & toddler groups, small injuries clinics maybe, then the high street could return to being an amenity for the community in which it is situated. In an ideal world!!
