In an ever changing World. What will the UK be like in 25 Years from now?

I think it will be like in South Africa where you have a MASSIVE gap between the "Haves" and the "Have Notes"
Where you have private estates with locked gates and lots of genuine poverty (By poverty I don't mean not having a Playstation 3 or iphone 5. I MEAN POVERTY)

I agree with your assessment.
