As a "young" economist, I can say that Steemit has one of the best Economies at the moment according to my current observation. They took all the "things" that bank's kept hidden or covered in "scientific terms"that are hard to understand by the public and fixed them. The only flaw in a system like this, are we, people. The system is perfect (to my opinion) but people aren't. We are the ones that will influence the future of this system and it's outcome.
