Proportional Representation would provide more high quality Government Services

People vote for high tax parties, in part as a consequence of the lack of proportionality in the voting system. If we had a more proportional system then people would be more willing to vote for Liberal parties because they would feel able to involve themselves in addressing the concerns that are the reason why they (otherwise, now) vote for Socialists.

If people are worried about a lack of healthcare then they would vote for a more Socialist party as a consequence, but if they could vote within a PR system they would be more relaxed about a more Liberal party. Liberal parties would do better in a fair voting system because people would not be so concerned that important Government Services would be neglected. Proportional Representation is better for Government Services because parties would compete at making the services better and more efficient.

Proportional Representation would improve Government Services because parties would be more incentivised and more willing to make a difference. A party which makes no efforts to make sure taxpayers' money is spent wisely would lose votes. We would vote for a party that makes good use of our resources, and is thrifty.
