Remember, the social Democrats sided with the Nazis over the socialists. They’ve done it every time they’ve been given the opportunity, and will continue to do so as many times as people fall for their shtick.

I like representative democracy in theory, our current implementation in the US‡ has a few major issues in that each representative doesn't represent the same amount of people. And we should have a lot more representatives for the people.
Not everyone can dedicate the necessary time to be fully engaged and informed about all the intricacies that come from running a government, so some form of representation is needed. But ~500 people representing around 300 million people is not nearly enough for the national stage IMO.
‡ I'm talking about the US here because that's where I live, but I'm sure other countries have similar issues though.
