There is no good money in it, he makes money so he can make these videos, not the other way around. If he makes money it can't be more than what you'd get from a shitty manual job.
Nope.
I know a little about youtube - I live with someone who has maybe 6 million views on youtube.
I'll give you some numbers, not even the best numbers. Better deals for more popular channels.
Roughly speaking, you pull minimum $2-3 per thousand views for monetised content.
The relationship divorce video has 260k views.
IE, he has made a minimum $520 - 780 for fucking waffling on about his girlfriend. That's just now, too - it could very well continue to earn for him for a long time.
Now, before you deride that as rubbish money, the videos he has since posted this last week up to the divorce video comes up at about 925k views.
Or 1850-2775$
Perhaps you consider that still to be manual labour money. Well, here's the thing. His channel has hit the point where it just fucking grows and grows. His 160k subscribers will probably be 500k or more by the end of the year and that means more and more money for him.
I don't really dig the dude either, but he has hit the critical point where youtube is a really profitable job.
