Think of the ten most objectionable people you know, and then imagine them, and more like them, and worse in power. It might make even the current shower seem OK, and that is a tough thing to achieve! (That is apart from complete novices being even more vulnerable than the current mob to manipulation by the permanent ruling class in the form of civil servants, business lobbyists etc)
No, the thing is not changing the people at the top (certainly not for people who might be worse!), but changing the structures and sharing economic and political power out more fairly. How you work towards that is the question....
