A great question...
In the private world, it seems like it is Sebonack or nothing. Or Liberty, or Bayonne. The enormous cost and personal willpower needed for land acquisition, permitting, professional study, design, construction etc has deflected the traditional, affluent, bourgeoise class who have made or make the equivalent of a 300K - 900K from congealing in any great number around the traditional "private equity country club" from scratch.
It is either the Masters of the Universe creating uber-resourced perfections or it is not.
No longer are courses created by country club founders from the normal professional classes of merchants, doctors and lawyers that will perpetuate through their children and become the future family country club. This was the dominant aesthetic, post WW II. Suburban land was still in play and costs were such that a prospectus for your own enclave was within the means of a greater number of merely "successful" people.
Now, those people play Centennial, River Oaks, Oxford Greens, etc (here in WCT). Or join existing clubs of whatever character they can afford. The experiences such places give and the money they charge is often so ridiculously incongruent...as to make me think they will go to seed within my lifetime.
