The only way for the traditional high street to survive is doing something like mike ashley's idea which is a online retail tax which the revenue is then used to subsidise high street rents/rates. But gov's are too scared to tax.
I completely disagree with his idea. Why should i have to effectively subsidise (by way of this tax) a company that either a) i would have no intention of visiting anyway, or b) hasn't made any attempt to change with the times.
As sad as it is to say, the high street is dying.
People would much rather be able to order what they want/need from home/work/on-the-move and have the luxury of having the item slightly cheaper, than having to visit a high street for it.
Subsidising high street stores by way of a tax isn't suddenly going to increase the footfall into these stores. It'll just make people more miffed that they've gotta pay slightly more for the product that they're ordering online.
I see 'Super Malls' (free parking / variety of shops / restaurants / bars / Entertainment - Cinema/Bowling/Mini Golf etc / All under one roof) being the thing that will attract people from high streets. The only flip side is that these only tend to exist in cities.
The home town where i grew up has a dire town centre that's been dying for many many years. The locals have been moaning for years that the council haven't invested there, and now it's full of economy branded shops. Everyone jumps on the train or drives to the next city over, which has a much more active/lively shopping scene.
