If the average is just $2.11 it means that close to half of all steemians will learn less than that.
The reality is that most people do not have a following. Without a following, you are lucky to earn even 1 cent. I had to write around 20+ blogs before I had even 5 followers.
People who join steemit see some famous bloggers collecting $100s and they wish they could have the same. The difference is that the famous bloggers have over a 1000 followers, whereas those who are new to the platform have none. It's like trying to be a pop star. If you have no fans, you won't be heard. You are singing to an empty auditorium.
A big payout is not relative only to a "famous blogger" but to influential followers and bots
