A guest in John Batchelor was a classic case of “projection”, where you inject your own opinions onto other people, believing they share your motivations.
The guest said multiple times that the motivation of the people who voted for Brexit was “they want to be rich”. Not even close. They are fed up with being trapped in their homes, unable to walk down the street without being attacked by groups of unemployed immigrates who hate England. The EU declaring that the UK would be fined for each immigrant they refused to accept was probably the last straw.
