First past the post is economically left wing

There is no reason for the electorate to be economically to the left of the government because it is the government which spends the money. Governments (especially when they are undemocratic) are economically to the left of the voters and it is for this reason that democracy (which brings the government closer to the people) is liberal. Democracy (where there is a state) is good for the economy because the people will never want a more economically interventionist government than the government itself wants. It is not the case that the government is reticent to tax the people and provide public services in the face of encouragement from the people. Democracy gives the people an opposing veto against the state. Democracy is only bad for the state and the state would become larger without it.

Democracy is economically liberal which means that any party which opposes democracy and proportional representation (where fptp is in use) is economically conservative and interventionist. The opposite of liberalism is conservatism and so economic conservatism is the same as communism. The two main parties which oppose pr are then protecting the state from liberalism which means they are to the left of the people.

The people are economically liberal in the main which means that any system which is less democratic than proportional representation is to the left and bad for the economy. The two main parties which support fptp are to the left of the people since even if the people are pretty left-wing the government will always be more interventionist than the people and so then democracy leads to liberalism (in contrast to the state).
