For many 'young' people their first camping experience will be at a festival, no wonder they pick up such bad habits.
Agreed, it's a very sad thing. I used to go to a lot of festivals, but I don't anymore because I don't enjoy them, perhaps because I'm old (you know, nearly 30), but mainly because they make me sad and/or angry. Particularly the ones with a liberal, environmentally-conscious image (e.g. Glastonbury), which actually turn out to be conventions to see how much litter and cheap camping gear you can spread over a small area of countryside while moaning about capitalism.
On the plus side, I have a lot of gear that I've "wombled" from festivals over the years...
My best was a six man high-end Outwell tent, which I packed down into it's bag, still with the labels on, at Leeds Festival circa 2009.
Several other tents still in use for car camping. I've never purchased a tent.
My mini tarp, and numerous other things I've made from a cannibalised festival tent.
A heavy-based saucepan, with lid, which I still use most days, possibly from the same Leeds festival as above.
Sorry, that was a bit of a thread diversion, I headed off down memory lane for a bit.
