If basketball stars and billionaires are opposed to denser housing near them in Atherton, California, where are there wealthy residents of the United States willing to have denser housing near them?

Atherton is a small suburb – under 7,000 residents – with a median household income of over $250,000. In question is a California effort to increase affordable housing.
Are there any or many communities in the United States where the wealthy do not pursue NIMBY policies?
Could it be different in places where wealthier residents can escape by living high up in the air? I am thinking of residences like the pencil skyscrapers just south of Central Park or the new condos south of downtown LA.
Or, could it be different in places that are more rural? According to Wikipedia, Atherton “has very restrictive zoning, only permitting one single-family home per acre and no sidewalks. This policy that prohibits homes from being on less than an acre.” But, imagine a place with even bigger lots and more room. Would denser housing in part of the community be perceived as less problematic by neighbors?
I am open to hearing about wealthy communities where affordable housing is desired and pursued.
