I think I would agree with you that Honor Oak actually has a higher status than most of Forest Hill. I used to deliver leaflets over a wide area and I noted that virtually all of Honor Oak is at least middle class.

If you move south towards Sydenham there a fairly high number of lower / working class residences. In other words this strip contains a mish mash of social classes (Unlike Honor Oak its inconsistent).

I noted the Upper class of Forest Hill mainly live in the Canonbie Road / Horniman gardens area but some people would argue thats a part of Honor Oak.

Since Honor Oak gots name from Queen Elizabeth 1 it could confirm a higher socio economic past. She visited the area and picknicked under an oak tree. To honor her visit you get the name Honor Oak.
