Having been on a board, I have seen the same with respect to course work. It is truly a shame given thousands of courses are doing the same, spending a lot of money for new tees, bunkers, moving greens, etc.
The 'ball rollback' has been argued quite a bit on GCA, not as much as origins of Merion East, but quite a bit. Way back when, about 6 years ago, we discussed the issues for a few years, and the subject surfaces about once a year. This has included discussions of a roll-back and how it could be accomplished fairly easily. It could be approached from several aspects. For example a minimum spin rate could be set.
Golf balls, and brand new 'name' golf balls can be obtained for $12 a dozen.
By the time you figure in research, materials, manufacturing, advertisement, packaging, shipping, profit for all parties, a very good golf ball can be bought at $1 each.
Of course, we all know the ball and equipment will allow for even longer distances in the future. Until research departments have no budget, the quest for more distance will continue. And the manufacturers will succeed in finding more distance. Of course, many have said this is the end, the ball can go no further.
It would only make sense to roll back the ball every now and then, regardless of how distance is gained.
Get ready for more bunker and tee work in about 5-10 years.
