Absolutely nothing would improve global society and standards of governance more than "commentators", politicians, think tank wonks and the other talking heads being removed from the media. Alex Jones, Owen Jones, Van Jones, Nick Ferrari, that cretin Scarborough, Solovyov, Tucker Carlson, Paul Mason and the rest - put all of them in the bin.
The only people who should be asked their opinion on matters by the media are the people who actually know what they are talking about (so experts in the particular field in question) and random members of the public stopped on the street. If the expert needs an hour to explain in detail about a complex issue, they should be afforded that time.
