I am arguing that pointing to the fact that the owners of right wing publications are very wealthy is not evidence that somehow consent was manufactured for Brexit, since the owners of left wing publications are also very wealthy. Owners of large businesses are usually very wealthy. Doubly so with publishing businesses, which are often unprofitable, and, thus, require a wealthy benefactor to keep operating.

And pointing to fact that Brexit was a non-issue a few years before hand is also irrelevant. There are a myriad of political issues being hashed out now that weren't on anybody's radar a few years ago. This is a normal part of how media and popular culture work.
