I've said it for years there's a huge push from fishing and shooting to get "youngsters" into the sport "because they're the future" (ever since I started shooting 5 years ago).
Yes. They are the future - literally. Likely 5-10+ years down the line before they even start thinking about shooting independently.
What about those 23-35 (ish) folk who are as Pedro pointed out, the ones with the disposable income? What if they want to get into the sport but with no assistance (as there usually isn't). That was me in the most part. It's still a very, very expensive hurdle... And arguably, these are the much more present future of shooting.
Another observation, there is unending amount of "city/townie" blame game for everything anti-fieldsports. But consider how accessible (or more correctly, inaccessible) shooting (and fishing) is to people who live in a larger town or city. Car ownership in cities is perishingly low, towns better, but still not an easy expense. I don't know of a single shooting ground in Scotland that is accessible by public transport, same with trout fisheries (although maybe 1 in Edinburgh you could get to by bus).
The £50 some pays to just to do a 10 or 20 shot clay taster is just the tip of the iceberg on how the fieldsports are pushing the town/city vs rural divide wider.
(And before anyone starts, yes I know plenty of people who also live in the city that shoot. The vast majority either grew up in families that shoot - usually based outside of city life or absolutely minted, or are individually wealthy that such concerns aren't a factor - these ones also usually work in circles where shooting is a thing too. So again, they all generally have someone to take them shooting to support them getting up and running with it)
