It is, but if we change it to the proposed system then we end up like Europe where all the same parties are entrenched (essentially no difference than it is for us now), and they simply create coalitions to subvert the will of the populace (they've already done that before in Canada) and get whatever they want to do themselves any way.  Universal suffrage itself, is a problem.  It's mob rule essentially, just less direct.  Not everyone deserves to vote.
