You got any evidence for this being the reason? Whilst I agree that the cost of living is a factor I suspect it's far more likely that many youngsters are just not interested having not grown up with the idea that guns are potential fun. Outside of the Public Schools where would kids get any exposure to firearms and more importantly their parents will also have none so less probable to influence the kids.
It's the same with motorcycling, largely a preserve of old farts like me.
Theres tons of evidence from the USA, there they rely on shooter $’s for their income so they’re motivated to find out why it’s dropping off.
Up to 18- 20 kids are reliant on their parents and their parents take them out and subsidise their their shooting.
Once they leave college the real world kicks in hard, they need to start paying bills, building careers and relationships, buying houses and cars and just when they’ve got that sorted they get kicked back to the poverty line once they start having kids.
When that happens, your disposable income vanishes down the same plughole as your free time.
Then theres the sad fact that most of us make our living in an urban environment, there just aren’t a lot of 6 figure salaries to be had around rural areas. You can commute to work on public transport, but you need a car to go shooting.
Shooting itself of any kind is expensive or you need contacts, please dont go telling me that you get all your shooting for free, if you do you’re exceptionally lucky, or you own your own land. Frankly, free shooting is not available to most of us.
For most of us it’s expensive, hard to come by, and if you can’t take it, theres a long list of others who will.
Its a crowded land, and the guy with the cash wins every time.
