It's all a matter of perspective and marketing, I gather.
Club boards have always followed someone or something in making their decisions. Typically, it was the PGA Tour, Augusta, or the USGA that set the tone. Or, Golf Digest top 100 lists. Or, hiring signature architects and telling them to copy the style of their most successful courses. A few times, it's way overspending to satisfy your ego. (The signature thing has never changed, and I can't tell if overspending is increasing, or we are just looking at the inflation dollars)
Now, it's a new breed of gca's trying just as hard to schlepp restoration as the 1950's guys trying to sell modernization. You have to discredit all that went before to make a point of doing your style, no?
And, BTW, the opinions expressed in the OP (and on most of this board) relate mostly to the top 1-2% of courses. I can assure you that public courses and mid level country clubs are still in the strict mode of "spending less nearly always beats spending more." And, it does seem as if businessmen don't manage the money at their clubs like they did to become successful business people, but that is anecdotal.
Lastly, while there is some truth to the OP, one truth is also that the attitude expressed, in either original quote or gca enthusiasts, is terribly arrogant, and part of human nature, to want to feel superior to others, sometimes resorting to name calling. It may be true that a small portion of the gca community is trying to be tastemakers (or changers) and that has always happened. It's just that you shouldn't necessarily belittle all the folks who don't happen to agree. And, I agree that my generalizations above do NOT apply universally, either.
