I've known plenty of "rich" and "poor" skaters, both have had success. These days I notice a lot more children of wealth in skateboarding though. Lot of 12-16 year olds who own a fresh iphone, wear polar/butter pants, dunks and always have fresh setups. They have all had skate lessons/coaching too. Not a chance I would've been bought any of that, a fresh deck for my birthday or christmas maybe.
My maybe unpopular opinion though is that sw360 flip lipslide (or blake carpenter's tailslide recently) to rolling out forwards is kind of lame and feels like an unfinished trick for a pro to me. like, you're obviously just falling out at the end and not really controlling the trick. (well aware that I could never do this trick and that a phenomenal amount of talent is required). it's just aesthetically wrong to me.
