Melvyn, most if not all American clubs lease a fleet of golf carts because the average US golfer is over 50 and prefers to ride rather than walk, particularly if it's hot etc.
(I agree this is not a wonderful situation but the horse has been out of the barn way too long to turn back the clock, say to the '50's.)
So now the clubs lease, or sometimes own, this fleet of carts. The more the management, even if it's a committee of members, can persuade the members to ride and pay a fee, the more net income the club can make. Once that projected net income gets on the forecasted income statement, it's nearly impossible to get it off, and subtle pressure will build for the members to ride.
It is too bad, but there it is. The irony is that I don't think most clubs correctly account for the cost of operating a fleet of carts, and may not generate as much net as they think. For example, are the amortized costs of cart paths included in life cycle cost analysis, or the annual costs of maintaining those cart paths? I doubt it. There are staffing costs that are probably not segregated.
