It's blatantly obvious that you have not been near Glasgow for a very very long time.
Glasgow has enjoyed much regeneration/rebuilding in the last 20 odd years.
In fact "The Gorbals" have totally changed in the last 20 odd years - it may still have high rise flats but many of the awful "slums" are gone giving way to lovely new builds. Of course, it is not one of the best areas in Glasgow but every city has good and bad areas. Even in areas that are not the best, many of the people are still the best!!!
I speak not as a Glaswegian but a Paisley Buddie that is at present working on the perimeter of the Gorbals.
The Glasgow Green is just across the River Clyde from my work. It is used for many things - Pipe Band Championships/Concerts etc
