There are multiple youtubers who have gone into depth about the details of how twitch people get paid. From top end to bottom, it's fairly consistent (except for a little subscription margin step at a certain point). Youtube/Google is even less involved in day-to-day, so there's no reason to believe that the scale isn't similarly linear.
My God, no. It's not anything like linear. It's more like exponential: the top earners are totally off the charts, and everybody else is largely jockeying for position.
I hesitate to even call it a scale. These things all follow viral dynamics: if you haven't blown up with billions of views, you're very possibly spending more than you get back.
Pareto explains the curve, but the monetary rewards are linear to where you are on that curve. Perhaps a small example will clarify.
Pareto Curve (more or less) of Y values on index X:
[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,2,2,2,2,3,10,50,500,7000,9000000]
Index 30 is "off the chart"
Now revenue:
$$*index
The correlation is linear (basically). The top youtuber who is a kid who reviews toys, makes the majority of his 22mil from ads, same as you or I would with <100 views per video.
Do all film actors make $60M/year just because Dwayne Johnson does?
