I think a lot of the time there's an implicit clash of classes there.
The people that lived it often can't buy the nicest gear and stuff, or if they did it's because it involved real sacrifice and dedication. Historically, they fucking made it themselves because it wasn't something you even COULD buy if you wanted to. So seeing some rich kid duplicate your drip overnight just because they can rubs people the wrong way. And I kind of get it: it's counterfeit. Its the same disdain people have for anything not made by a real artist but passed off like it is. They show up with all the nicest shit duplicating your real effort and struggle, but not having done the work.
A lot of those poor kids only have that thing in their life and the crowd dedicated to it because their homelife sucks.
Most the skaters I grew up with that were really good were that way because they suffered. They were out skating after-school because there was no family dinner and warm welcome waiting for them at home. We were our own family and support. When a friend of mine handed me down a box of old gear so I could put together a new-to-me board , that saved me months of struggling to come up with the cash to replace a board that got stolen.
And honestly the skaters kids were the most welcoming group I ever saw. They took in all the otherwise rejects of society. But no one likes a poser.
