Proportional representation gives more reason to vote

If people are not able to vote in a 'naive' way, that is to vote simply for their preferred candidate without having to be concerned about tactical voting, this is helpful to the establishment who want to act against the wishes of the people. Because a non-proportional system protects the state then the state can retain unpopular policies more easily if there is less democracy. If the voting system tends to favour (for example) just two parties then if voters cannot abandon both for a third party, the two parties remaining are able to share policies which they would have to abandon if more choice is given to the voter. First-past-the-post protects politicians from the voters and consequently it protects policies from the voters.

Because first-past-the-post makes it difficult for voters to alter the policies of the government, it reduces the incentive for people to vote and if the main policies which people want to remove are shared by both of the main parties there is no point voting, with a non-democratic system. If there is more democracy there is more reason to vote because it is easier for the people to alter the policies of the government. If there is less democracy, as with fptp, then people will have less incentive to vote. Proportional representation would give people more reason to vote than with first-past-the-post.
