First elections are not just a retrospective vote on how the government did, it is also about what political parties want to do. Yes a few elction promises get dropped but the vast majority stick to their promises because they know that not doing so will result in them losing the next election. It is simply not true that representative democracy is oppressive. If people aren’t happy with the way the government is using its power they can vote for a candidate who promises to undo what the previous government has done, or they can even enter politics themselves. The people can always take back powers that they don’t want the government to have by forming and supporting a party or a lobby specifically for that purpose. The reason why this hasn’t happened yet is that most people are happy with the representative system and do not feel like their liberty is being violated.
