Because golf clubs struggle to recruit intermediate members and see it as an incentive to safeguard the future of the club. You make out like 20-30 year olds are pining for reduced fees - it's not the case. I can only assume that intermediate members are seen as a valuable commodity by golf clubs - otherwise there wouldn't be the incentives there are to attract them.
Simple - potential intermediate members have in general the greatest amount of flexibility in their life. But get 20-30yr olds in; keep them - however you can; have them build a loyalty to the club and a social circle within it; you have a chance keeping them when they get into their 30s and maybe have family and schools. Besides. Younger guys want to associate with at least a few like-aged and like-minded. A clubhouse full of over 55s may not give out the right signals to a 25yr old prospective member.
