lol idk where you're looking but most "youtubers" start their own clothing line lol.
also seems like you're jealous of them buying expensive things haha. they started a channel got "big" or "famous" and they spend their money, just like how every normal person would.
if you're talking about Jesse Wellens, he is one of my inspirations for film making etc. aside from the youtube stand point etc, as a film maker in which he is, i am inspired by that. he kept making films etc, and look where it got him, a music video for Snoop Dogg. lol if he wouldn't have put up films on YOUTUBE then he wouldn't be where he is today lmao.
Teespring doesn't really count as a clothing lining. Its just shitty mech they sell for a quick buck. I'm not jealous of YouTubers, I literally said Casey Neistat (a famous YouTuber) who used his YouTube to build a company/drive traffic to it and sold it for 25 million bucks. He is my inspiration. Look at where he is now in both a film making, business and financial perspective. Casey took his YouTube cash and turned it into 25 million. Every vlogger is a Casey wannabe. Jesse is just a rip off of Casey Neistat.
