I'm not sure that there's a workable alternative available. When a population's choice is divided among multiple 'parties' and 'ideologies' it's uncertain that any consensus is achievable. While differences in policy and philosophy may offer the appearance of "choice", whether it's two parties or twelve parties, the dynamics of state governance will be focused by the particular dynamics involved regardless of the choices being made. In Canada and the U.S. our societies are so wholly given over to maintaining the status quo..protecting the wealth and authority of the elite, that change is extremely difficult. I'd suspect that change would be just as difficult if not more so if the complexion of the political canvas was broadened to include even more hands eager to secure a spot at the public trough....
It's a moot point and deserves careful consideration given the history of government in Canada and other democracies whether there exists even the possibility of government able and willing to live up to the tenets and ideals of a truly democratic system.
