Have you done the math behind it? Do you think it will solve the problem? If so, how? Perhaps pitch the idea to the witnesses. You will have to convince them of the change. But that one simple change will impact the whole system. I doubt very much you would get a consensus on that change.
There is nothing wrong with the system. People are the problem. Always will be too. So how do we fix that problem?
Of course I have not done the math behind it! :-) Not vested enough to take the time. I see it solving the problem in the above scenario as the bankster would not be able to feed the greed as his vote would be the same as everyone else.
I will continue say the system could be better but because of the difficulties in changing it will leave it alone for now. I agree that consensus would be extremely difficult as many steemians are invested in building there accounts on the increasing power and weighted voting. The impact would be huge.
Totally agree people will always be the main problem and that is best dealt with being a good influence. Walking and talking the walk and talk.
