I think there is a market for the 20 and 30 somethings. A lot of the people i teach and speak with are in this age range and would love to join a club but can't afford it. They play a few times in the summer months but finances restrict their membership options.
Why not. Most would (should) be in gainful employment. OK granted I know there are redundancies across the board out there but in that case joining a golf club wouldn't be high on my list of priorities anyway.
Most 20-30's will have done uni, got a job and moved away from parents. I accept that a lot of clubs still have joining fees (especially around my area) but even these are coming down and variable payment plans being offered. If you have other committments (family etc) and a limited budget then I'm afraid the harsh reality is you can only make money go so far. Joining a golf club is a luxury and if you can't afford to do so at the moment then either play P&P as much as you can, look at 5 day (cheaper and you can still get a round in every weekday night in the summer) or save.
Blunt but realistic. I was made redundant about 4 years ago and really struggled to find the money but evenutally went onto monthly DD for a year and begged and borrowed enough to get by until I got a job again. The club wouldn't hold a place open (and why should they) and there was a chance I'd have to start from scratch if I left and rejoined including a % of the joining fee which is why I didn't want to lose my membership and did everything I could to keep it.
As I had a lot of time to play in the early summer too the handicap dropped and I won a few medals so every cloud and all that.
