Yes. The economist is mainstream. It is a very old publication, run by professional journalists with expertise in the subject on which the write. I'm not sure how this is a bad thing.
The best way to understand how the world works is to learn the orthodox mainstream version and then round that out with alternative sources. If you totally ignore a publication like The Economist and get all of your news from partisan ideological sites then you're being fed a bunch of nonsense.
