It pretty much always has been. As a rule, the Good Old Days were usually worse.
I'd agree that the Good Old Days were usually worse... but politically the early 20th Century seemed to have a much wider range of competing ideologies, all promising a better world - from communist utopias to the freedom of the capitalist markets.
Voting for a particular party would help to make that dream a reality and lead to a better world.
Now it seems politicians never talk about making a better world, just maintaining a less bad one and how voting for them will protect us from some unseen and statistically unlikely attack looming just around the corner.
(Disclaimer: I wasn't there, you might be right... but from watching old speeches and what I know about early 20th Century politics my argument seems to hold)
