As with anyone, leaders of countries act in their own best interests. However, the journey to the highest levels of leadership requires a particularly power driven mindset or else that person will not get the opportunity to lead.
Representative democracies consistently offer the same types of leaders with very similar mindsets and ambitions.
You would have a difficult time finding a leader who has gone to great effort to obtain power just so that he or she could genuinely give the power back to the people.
Of course now I understand you. The core of representive democracy shouldn't be like this really but I guess e humans have defined it differently with the modern rulers we have in power nowadays. However it's really pathetic, people should be the focal reason for representive democracy sadly this isn't true. Thanks for replying.
