An American parliamentary system with proportional representation wouldn't immediately or inexorably lead to a flourishing social democracy, but it would at least correct the overrepresentation of an ideological minority and cut down on intentional tactical economic sabotage.

Social democracy does not represent an ideal future; it does not even represent the ideal past.

Passive fatalism can never be the role of a revolutionary party, like the Social Democracy.

Between social reforms and revolution there exists for the social democracy an indissoluble tie. The struggle for reforms is its means; the social revolution, its aim.

My definition of democracy is -
A form and a method of Government whereby revolutionary changes in the social life are brought about without bloodshed.
That is the real test. It is perhaps the severest test. But when you are judging the quality of the material you must put it to the severest test.

Journalism is what maintains democracy. It's the force for progressive social change.
