I can't hate on any of them, because what do you expect? Most do it for fun and accidentally become big, and when huge checks start coming in the mail what should they do? Say "this is a bad idea, I'm a horrible person for trying to entertain people!" and quit?
Come on now, you gotta admit there's some major jealousy in this thread. Understandable, but justified? I'm not sure.
Most of the 'big' youtubers got there by accident/snowball effect/word of mouth(not their fault)/being regular content uploaders and actually caring about their channels. It's sad that many channels sit at 300 subs or 3k subs but its a big world. Not everyone can get lucky.
Also it's a website for amateurs to entertain people. What do you expect? You can't expect much. And if you think you can do better, maybe you can. And you should try. To paraphrase Lewis of the Yogscast: "I thought I could do a better job than some of the channels I've seen on youtube" and he has. His channel (through a collective effort of all of the yogscast) now has 3.5 million subscribers. But it never would have got to that point if he never tried, never thought he could do a better job.
I say well done, they deserve the success they've gotten!
Okay, one more corny paraphrase... uhm, from Gandalf. The Wizard. "Some that fail deserve success, can you give them it? Do not be so hasty to deal out judgement and criticism". Okay, so he didn't say that at all and he was talking about life and death, but dangit! It fits! kind of! that's what she said! Okay I'm not making sense anymore...
