Sad but true ... As for answers, well, they are myriad .. but ultimately they are all flawed because human beings tend to be greedy.
Design something for the masses and there will always be one person looking at how they can hack it to make themselves wealthy!
Any solution has to be designed to address that very human failing.
If you don't engineer equality, then you can guarantee that you won't get it, irrespective of the intentions of individuals or the system adopted.
As your infographic clearly illustrates, it only takes a small and greedy minority to screw things up for an overwhelming majority.
