I think one of the main issues is the little, or sometimes big number underneath the posts. 

Lots of people are just jealous that they didn't know that they could easily create a simple 5 minute video with a 20euro webcam and no other investments than a bit of time to make a years worth of salary Or that they didn't think of that specific meme. 

So if  people don't know about the sum of money a post generates I believe that the focus will go back to the content. This would at least remove some of the hate and pathetic posts around here.
