That's exactly what they do. It's actually another unsuspecting process of the "Transhumanist" Future. A Future where there is no such thing as privacy, as earning, and where people pay for advice and attention instead of meeting for coffee with friends and buying them a coffee.I wouldn't be surprised if YouTube sort of "leaks" out some kind of unrealistic way to estimate how much you can make on the channel, in order to attract people to it.
With using the estimates / projections for even unmonetized channel, it makes people get suspicious or jealous of thinking people are making money even when they might not be at all, or people will size others up based on how much money their channel earns or would earn.
I've watched how YouTube has evolved over the years and with finesse they have gradually been reprogramming everyone without them realizing what's going on. It used to be all that much more fun and novelty when it was a New thing, but not so much in the last few years.
