I was going to say if you want diversity, you should just be a public course open to all. But really whether the course is public or private, it is economic disparity that gets in the way of diversity. It’s the same dynamic that makes it impossible for a brand new course to be as “affordable” as some people want it to be.
Your second and third sentence explain why the first sentence wouldn't really promote diversity(at a new build).as it would be cost prohibitive unless different rates were charged for different demographics-an untried and slippery slope-but an interesting concept.
Many/most private clubs have excess capacity that can be used in a variety of ways though a bit of creativity,cooperation and flexibility with the maintenance crew may be required.
A well managed private club,in the proper demographic can subsidize and provide that capacity/opportunity to those not in that same demographic-if it chooses to, especially if the members and owner know what the mission is they are signing up for.
This can be especially helpful if the members embrace the mission and include the diverse in their play, thus reducing the strain on capacity by simply filling out a foursome or threesome, rather than creating multiple groups.
Not easy, but if it were easy, more clubs would already be doing it.(to be fair, many clubs do this to some degree with High School and employee or caddie play)
Kudos to Nick for trying to expand on this.
The trick is,being able to match the time the capacity is available, with the schedule of the diverse they are seeking-no doubt a very difficult task.
For example:his LPGA support could work easily as they(living on site) would tailor their practice and play around peak member times, and at peak times ,integrate their play with members as well, enriching the experience for both members and aspiring players.
Not so easy-HBCU and High School programs which may have an academic schedule similar to many member's work schedule, but in theory the High Schoolers would be working in peak times and playing/practicing around the edges of work and school.
There's ALWAYS time for a game early in the evening April-October for those not bound to social engagements-which it seems so many are.
