You have a point. Although I think we can test with different blockchain settings, all those coming here for the money, will not be satisfied; not in Europe, not in the poorest country we have on earth. When Steemit grows to eg 10m active users, each posting 1 post per day, each user will in average earn about 0,005 Steem which is about 0,01 to 0,015 US$ct. And since any system will always have large out performers, the rest get easily 5 to 10 times less.
Yeah, this is an opportunity not a job. It isn't meant to be sustainable.
