Brexit was not a unifier. Just the opposite.

The UK's real issue is that it is a corrupt hollowed-out plutocracy run for the benefit of corporations and privileged opportunists, many of whom live abroad. They control the media, they buy politicians, they own much of the land and property market, and key companies and resources, and they set the narrative.

They have no ethics beyond power and money, and their signature attitude is contempt for voters.

The result is PR politics where major issues are ignored - climate catastrophe, the dire state of many utilities, lack of investment, lack of national strategy - and the media concentrate on fear-mongering and distractions, including racism (esp. Brexit and Islamophobia), punching down at the weak, and aggressively disproportionate punishment of very mild public dissent.

A series of comically incompetent and personally grotesque figurehead prime ministers - who can be talked up on installation and trashed when minor release is needed - is just another of the distractions. It simultaneously enrages the population, forces them into apathy (because nothing fundamental can ever change), and reassures the country's owners that money and resources can keep being extracted while the government "can't afford" more spending on healthcare, education, and critical infrastructure.

If you're thinking "That sounds like the US" - yes, it does, and that's not a coincidence.
