People make youtube videos because it generates income
It wasn't always this way, plenty of people made great youtube videos just for fun before there was any kind of "monetisation". Sure, there weren't the highly polished big budget videos (which would probably have been on tv back in the day), but there also wasn't all the like-and-subscribe sponsored shit which makes the internet so unpleasant nowadays.
YouTube is good because there's money coming in and going out
So yeah, I can't disagree with this enough!
