No matter under what flavor of a system we are, the rulers are going to be corrupted by power, the elite are going to be greedy opportunists vying for power and control, the people will be oblivious and borderline retarded and anyone stupid enough to try to change anything will be crucified by the same people he is trying to save, either before he can even make any change or after the old powers have been overthrown.
You can change the system, you can change the rulers but you can’t change people, any system with humans in it will eventually become a corrupt hellhole with nepotism and cronyism running rampant until another group who has their heads together overthrows them and the cycle begins anew.
