Also any form of government is prone to corruption.
If you chose democratic-socialism = the head of state will turn into the king in time.
If you chose fascism = same thing.
If you chose democracy with capitalism = Basically politicians get bribed by corporations and people with hidden agendas get voted into power.
True Athenian Democracy was working very well until the Macedonian's conquered the city.
Of course, true democracy doesn't really work too well on a large scale for big countries like today, because it relies on people being given their positions by potluck and everyone has to vote on pretty much everything, the former of which would cause accidents from time to time as unsuitable people are chosen for roles, and the latter meaning that entire populations of millions would have to vote at the same time on any minor issue (which would be difficult to get people to do, and more difficult to get everyone equipped with the means to vote without all having to travel to Parliament each day).
I can't support a country that looks more grey in every picture than England's skies.
