With proportional voting, MPs, MLA's etc are chosen from party lists.  I've often wondered what the purposes of MPs in such a system are. In the Canadian system, all of them will be bound by the party whip and will vote for bills as instructed by their party leader. So what benefit are they. They just take up room in the legislature and collect generous salaries and pensions. Why not just give the party leader votes in the legislature proportional to the votes cast for their party. This is effectively what would happen anyway and the taxpayer would not be on the hook for all of the salaries, expenses and pensions.
