Agreed in part, but your attempt at it being only North South discrimination I don't accept. It not only happens down here, the defiling can be done by the privileged. Take Addington Palace on my doorstep, the fourth of the Archbishop of Canterbury's palaces (none at Canterbury!)
A magnificent palace in the Paladian style on a perfect south facing North Downs slope with the grounds designed by Capability Brown and having a world famous Cedars of Lebanon at the front:
The Archbishop finally left us to go to Lambeth Palace in 1850 and this palace became the home of the Royal School of Church Music, which in more recent times was a favourite private haunt of the Queen in preference to Buckingham Palace which she's always disliked.
Eventually the C of E's decline meant the school of church music had to give up and move somewhere less palatial and Addington Palace became a hotel for the privileged who promptly destroyed Capability Browns superb landscaping north of the palace by constructing a golf course over much of it, despite being touching contact alongside a large existing golf course. Not content with that, to reduce costs they gave up much of the southern half of the grounds to the council as a public park where funfairs and the like are held.
Ironically the hotel failed though the golf course persists as an exclusive golf club and the palace is now an exclusive marriage venue for the richest:
So the south also cops this style of destruction and the vandals can be the right wing privileged as much as the socialists of the left
