In practice, it doesn't work. The bias and delusional behavior of the editors is infectious, widespread, and has even been criticized by Wikipedia's own co-founder Larry Sanger as being overrun by "left-wing propaganda essays." He even went as far as to call it the "most biased encyclopedia in history" in an interview with Glenn Greenwald. (https://www.youtube.com/watch?v=YR6dO8U8okk)
Frankly, it does seem (following stereotypes) that left-wing people have a stronger tendency to be writers from being white-collar; while more right-wing folks are too busy with blue-collar jobs and physical labor to be writing rebuttals. A very simple example is how Wikipedia approves Vox, Slate, The Nation, Mother Jones, Jezebel, The Atlantic, Gizmodo, and Jacobin as sources, but Fox News is considered "unreliable." Permitting Jacobin and Jezebel, but not Fox, is delusional. (https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources/Per...)
