The economist is very heavily biased towards global capitalism, and they present many strong cases in favour of particular political paths. I’m not sure why so many of their readers see them as neutral, I suspect it’s due to the high brow nature of the writing.

At the end of the day there is no way to produce a non-biased publication, you’re buying into the stories the publishers choose to publish (fact based or not), your opinion is likely formed before you read the magazine.
