>Authoritarian voters support Brexit, liberal ones don't.
I don't think that's an accurate analysis. As far as I can tell the vote was driven mainly by economic distress, media (which papers you read) and community (a lot of people just voted the same way their friends or family did).
>The London Tech scene (which skews left/liberal) seems to be hemorrhaging talented people to Berlin and other places.
I know a lot of people in the London tech scene and I only know two off the top of my head who have gone to Europe, and I don't think Brexit was a major reason for either of them.
I also haven't seen much of a significant rise in rates. If all the valuable talent is gone surely that means I'm going to be worth more?
>Meanwhile, inflation is so bad the supermarkets are quietly reducing the quantity in boxes
That's how inflation always works in supermarkets.
