Luckily there are lots of different systems out there but not to choose from. Most countries are stuck with the system they grew up with. There are haves and havenots in all the systems.
Socialism promises a lot for the havenots but fails to deliver, being so uncompetitive generally.
Capitalism widens the gap between the two.
What the ideal is I have no idea. They all have their drawbacks and positives.
Oooookaaaay.....but then are we any further toward putative answers to the question in your thread title?....i.e invigorating UK business?
For myself, whilst the High Streets are indeed dying; to people who remember those halcyon days when they were central to the life of a community, it is indeed sad to see this rapid decline. That said, just as in the times before those same High Streets, there were different communities, there are different ones right now and in the fullness of time we'll begin to more clearly see the direction of travel.
We might not like it but the model that has been in place for 150+ years is finished. That does not mean that the High Streets will just crumble into dust but as all the commercial interests that drove their creation in the first place begin to adjust their own business models we'll see another shift.
Just because we may not have lived through a period when, say, the City of London was full of residential property and there was a far different usage mix than there is today, that doesn't mean that this won't change. As commercial and residential properties fall in sale and rental value with the decline in demand, then prices will also fall. At some point, properties will be repurposed where practical, or demolished and rebuilt....exactly has always happened.
I would argue that part of Pat's "reinvigoration" has already started with the enormous surge in change of use applications, modifications to planning regs and the fact that architect's practices are currently kept more than busy with conversion projects. I recall reading somewhere that some 30% of office space may soon be redundant..... and what about all that commercial property and the forest of Lease For Sale signs in every High Street?
In the short term, UK residential property prices will continue to rise but I wonder what will happen when even a modest percentage of inner city/town centre residential conversions begins to affect demand.
