Ya, so Steem is inflationary. Every day a certain amount of Steem I'd made. Some of it goes to the witnesses, the rest is split between all the upvotes on content. There is only so much Steem to give out though. As it stands there are 50k people on here a day, and haejin makes 5% of the total rewards every day. He makes over a million dollars a year just posting on here currently. Steem is to new and to young to be paying out any single person a million dollars a year, someday when Steem price is much higher, lots of people might make a million dollars a year on here.
