The whole point of Brexit was to destroy social democracy.
All the elements of social democracy - worker rights, environmental standards, democratic representation, a welfare state - will be replaced with profiteering and spivvery.
Of course if Brexit had been sold as that, hardly anyone would have bought it.
The UK is now in a race between fascism and incompetence. Neither is a good outcome, but an economic implosion followed by popular protests might just about turn this around before protest and resistance are banned by diktat.
From another point of view the UK hasn't been a true democracy for decades. This is the country which hatched a number of coup plots against Harold Wilson, who was a rather stodgy and mainstream left-of-centre politician by European standards, but was considered a Soviet extremist by the Establishment - while that same Establishment protected insiders like Anthony Blunt who actually confessed to recruiting spies for the USSR.
Blunt had gone to the right schools, so was given immunity from prosecution. He was allowed to keep his knighthood, and continued to work - for the Queen, no less - until he retired.
If the intelligence services had had their way the public would never have been told. The story only came out in 1979 because a journalist broke it.
The UK continues to be motivated by a very strange kind of class-based nationalistic extremism. Establishment insiders get almost infinite privileges, no matter what they do or how much they damage the country, while outsiders are treated with suspicion, contempt, and abuse.
Brexit is just the latest twist in that story.
