Ryan,
$85 is 77 Euros. I can afford $85 and I'm not a 1%er. There are always going to be high end courses. IMO it isn't due to rising maint costs, it's due to a group of people willing to pay that much money to play there. My price per round is not off assuming F&B isn't losing their ass. I think what sean is saying is there isn't anything wrong with trying to improve shoulder season conditions and those costs don't make green fees double.
Price per round even for those who are members at top 100 courses won't be more than £45 or £50 for most. Membership of a very good course can be had for £1,200 - £1,300 in south / south west England and much less in Wales and Scotland.
Price per round means expenditure divided by number of rounds played. Not how much was paid twice in Scotland on a mini tour, your figures are way off for the uk. Your low maintenance vision is actually in the high end bracket here.
High end falls into two categories. Those looking for return on their initial investment. And members clubs looking to subsidise the annual subscription.
Sean ain't banging on the Sec's door at Burnham about the sharp rise in green fees over the past few years. He like all of us wants his membership subsidised by visiting players at times that don't impinge on him. When he plays away, he longs for the good ol days.
I'd suggest the sharp rise in greenfees at upper mid and high end is due to the following rather than market forces: members wanting their cake and eating it. Those at the better clubs can and do it. And due to better clubs being scarce and a treat, we'll keep paying the high Greenfees and the members get top 100 golf at nondescript suburban prices.
Most clubs in this bracket are just breaking even and keeping modest cash reserves. They probably should charge higher subs and plan better for failing irrigation, dillapidated clubhouses etc. Golf clubs are businesses and even those owned by members should charge the highest obtainable greenfee to benefit the owner / member.
