One thing's for sure, something needs to be done to prevent High Streets up and down the country turning into ghost towns.
In an era of declining, finite resources, increasing unemployment/underemployment (with those in work becoming increasingly parsimonious/penny pinching) and the prospect of higher and increasingly unreliable energy supplies which will make manufacturing of brand spanking new stuff even loss cost effective, it stands to reason that turning the idea of what constitutes the retail shopping experience needs to be turned on it's head and reinvented.
Shopping streets, particularly in faceless large towns and cities, need to become a greater place for innovation, the arts, light entertainment, community, education, enterprise, recycling/second hand/'vintage' goods stores and socialising, just as much for satisfying consumer needs.
I have always thought that the 'in-shops' mini mart concept where small traders and services like seamstress businesses, shoe repair shops and little ironmongers etc are often based has been under utilised. They could really be expanded a fair bit in city centres, especially now that there will be a lot of people looking to become small-scale self-employed for the sake of doing something rather than nothing as redundancies increase. That's something that will be a lot easier with a lot of prime sites becoming vacant. (There's an idea for some entrepreneur out there!) A more intimate, down to earth shopping experience. Plus small co-operative ventures.
Plus during a major recession, people have a lot more time on their hands. Cheap and affordable, fun, escapist pleasures like going to the movies (as did gambling, boozing and prostitution unfortunately) became very popular during the Great Depression. The movies aren't so cheap now though. I wonder if there would be any mileage in converting High Street shop units, into little specialist boutique cinemas/cafes or something>? I've always thought it would great if there were cinemas that only play good classic films (Wizard of Oz, Citizens Kane etc) rather than all this mass-market muck or art house rubbish.
