Several issues here.
Not having a go at you personally but this post demonstrates how Neo Liberalism has entrenched itself as the "common sense" of society. ( As
stethoscope has suggested. Also my namesake).
The super rich don't have more ambition than anyone else. A local example is the Brixton Rec. This now has Grade two listed status. One reason is that it's good example of post war socialist architecture. After WW2 there was general feeling that ordinary people should have good architecture and facilities. The Rec is an example of that. Post war the normal career move for architecture student was to work for a local Council.
Thatcher tore up the post war consensus.
Now this society went backward. It's back to depending on philanthropy of the wealthy. Squires are like the Tate family who built the library. All very well but is this really the kind of society people want to live in?
One based around class?
I come from a cross class background. Father working class and mother upper middle class. I remember my grandmother. She could not get over the decline in deference and loss of prestige she felt her class suffered post war.( To add this was real. Ordinary people fought and defeated Hitler. No way we're they going to put up with a society run by my grandmother's lot post war) She had a real resentment. Understandable in a way when one loses all that.
What I've seen in my adult life is gradual change over 30 years to point where individuals like Squires are seen as a good thing. My grandmother would have approved. A change for the better. At last a return to a society based on philanthropy by those who have good taste.
In hard headed reality , whilst as individual social actors, I have nothing against Squires personally the Department building imo isn't socially progressive.
