I like to think of the whole thing as a game. There's this circle of elitists, the ones allowed to play, all of whom at one point or another were ministers or CEOs and every couple of years one of them gets their turn as the top player. Now this top player would proceed to "reshuffle" the current players, or if he's looking for some change, add a couple of new ones. The field that each player is in charge of is truly irrelevant to their area of expertise. Now once the parliament is elected, the game of who destroys who first begins! Fun fun fun.
So I don't really think it matters who gets picked as the prime minister, the same cycle of events seems to repeat itself regardless of how optimistic we are of the new government. But not to be part of the blame culture, because we should take the blame as well. We should be part of a responsible, incorrupt election that would result in a parliament that speaks for the citizens rather than attack them, but hey that's just wishful thinking.
Once again, Emad Hajjaj depicts it best.
