What kind of videos do you make? Maybe YOUR videos aren't ball busting labor, but why you seem to assume that you know the effort involved in everyone else's is beyond me. My channel consumes me, it's to the point that it's my entire life pretty much, I over think, underthink, shoot reshoot, edit for hours, spend hours brainstorming, it's not freaking roof tiling or construction work if you're just making a PHYSICAL comparison, but mentally and emotionally if you want to make GOOD videos it's freaking WORK. It takes an unbiased and ready to tweak eye, plus a desire to constantly be searching for the next idea, plus the dedication to spend tons and tons of time editing and tweaking to create something you think is worthy to be seen.
And sure man, most of the time they "don't know what they're doing" But from this forum if there's anything I've learned it's that not every youtuber thinks they're the next smosh. Some just like doing it, and could die happy if they hit 1000 subs. But this comment was tied into your last about how the big youtubers don't work hard. They might not NOW. Maybe NOW a script writer comes up with their ideas and a camera crew perfects their lighting. But to get that privilege they did it all themselves FIRST.
So you can say that making videos is never a hard labor till you're blue in the face. And I can say "f**k you it's become my most draining task in life" till I'm purple. At the end of the day, no one gets famous for no reason, even a manchurian candidate is picked for a reason.
