That's a slight exaggeration but the principle is 100% correct. I stopped listening to 5 Live a about 18 months ago ago as I was already growing weary of their constant obsession with Brexit, then Covid. Valid news items certainly but not the 24 hours a day they seemed to devote to them.
Then I was listening one afternoon and they were discussing some aspect of government economic policy. I've got an Economics degree & it's a subject I'm still interested in so I listened and they had two people discussing whatever it was. One was Yanis Varoufakis, the left-wing economist and former Greek Finance Minister and the other was from the Cato Institute, which is a Koch funded body. For those who don't know, the Koch brothers are very wealthy US ultra-conservatives who fund many like-minded think-tanks and other organisations. Both had an immutable ideological vew on the subject, on the extreme edge of the spectrum of debate. I'm always happy to listen to opposing views, as there can rarely be one single view on a subject, but this was two diametrically opposed extremes where there was no common ground or meeting in the middle.
I learned nothing from the debate other than the fact that these were the two most extreme positions. I complained that this wasn't "balance" but, as usual, the complaint fell on deaf BBC ears. So 5 Live got turned off and I don't miss it.
