Golf isn't "dying." There's been a correction of sorts going on for the last several years, which isn't unusual in any business.
We just assume that since interest isn't at the same level it was back in the early-mid 2000's that it's on the verge of shriveling up. Yes, courses have closed and will continue to close in certain low population areas. Yes, retailers have closed and will continue to close (a lot of that due to discount golf internet sales and eBay).
But it's not dying. The local muni will remain open. My private club is doing fine, because they're being creative and aggressive with their marketing approach and changing things up. "Stale" is dying. Facilities/businesses that have sit on their hands the past 5 years and can't figure out how to be creative enough to survive are falling off to the wayside and making more room for the better-run facilities/businesses.
It's really just the cycle of business in general.
And I do feel bad for the facilities/businesses closing shop... lives are impacted when that happens. But challenging economic times call for innovative leadership. And sadly, we don't have an awful lot of that today in America. We've got a lot of hard-working employees who show up every day, but leadership on the other hand....
