In any monetary system it will always be the mindset of human greed that drives it. You can see it here otherwise Bernie Sanders (steemits Sanders) wouldn't exist here. Let me also provide an example that happen the other day. Someone ran a contest. The object of the contest was to find someone(s) in the most need, food, medicine were listed as primary need though, as usual, people told stories of vet bills, or start up money for a site, etc.. The articles author laid out the rules, write a story, link it up inside the contest story and the one determined with the most need would win. When the winner was announced the author decided to break his own rules. He went outside and found a write up about a group of boys in a third world countries lucky enough to have a laptop and had made enough money off Steemit to buy t-shirts to hand out to kids. The group of boys stated that these young kids provided the t shirts were in a program for reading and writing and that once in awhile they stopped by to see these young lads. The kids were, I am assuming, (and based on the calculation of the above referenced article, they were richer for lack of debt) considered poor but otherwise looked happy and well fed. Most of the article produced by these guys focused on them and their success with Steemit and one paragraph about how they visit these boys once in awhile. How that fit within the boundaries of the rules for the contest I surely fail to see. It wasn't like these boys said they would buy these kids books or writing materials or donate the money for that cause, which still isn't feeding the starving but at least would have been a bit more credible. What the author did was greed driven, he saw a opportunity to increase his base by granting these boys the money, who then in turn follow him and more than likely find him more followers. So in essence he found a way for them to be indebted to him, he's greedy and rarely up votes his followers so their return for the debt will be minuscule once they spend their reward but his return will be tenfold. The moral of the story is is that when it comes to money, any money, man will always turn his back on the starving children of the world.
