To the question, there is old RSF and new RSF. Very similar dynamic to La Jolla
Old La Jolla people are generally very nice. Newer La Jolla residents are more materialistic, pushier and generally less fun to encounter. I think the analogy generally holds. Most snobbery stems from insecurity
RSF is different from LJ in that you are not on top of one another. You are paying for big lots and privacy. It is not a good place to raise kids if you want to keep them down to earth.
I am from pre-IPO san fran for reference. Unlike some of norcal, the rich here tend to show it (think 100K Lexus but not a Maserati) in their houses, cars, lifestyles.
I suggest you rent a house for a yr. The transition will be hardest on your kids so take their temperature as you rent.
