Brexit has happend, but the type of Brexit we get is still very important. Whatever we get won't be what most people who voted Leave thought they were voting for and economically it is going to be worse than what we had.
However, what is far more important is how we got to this point and what it means going forward. We now have a very narrow section of society in charge. They are largely of a similar age, background, status, education, married with 2 kids, basically there is no variety. They are naturally going to see things through the prism of their own experiences. This has been a trend for a while, not just this government. What is different with this government is that these people are also specifically chosen because they are largely of the same mindset and philosophy of Boris/Cummings. Most of them genuine believers, some because of ambition, courage, conviction, independent thought or integrity.
This is not a recipe for good decisions on behalf of the majority of the country. When you add to that the influence of those backing the Party behind the scenes (Matthew Elliot/Russians/Bannon/the people behind Trump), the takeover of the Party membership by the UKIP, the ERG party within a party, in the consideration of who comes first, the majority of the country fall a long way down the pecking order. Focus first will be on what the Party backers are paying them to do, then their members, then voters (as judged/swayed by Conservative commentators in the media).
On top of that, these people are used to lying with impunity and getting rewarded for it. They now believe they are right about everything, because they won the vote on Brexit and then people endorsed them at the last election. In their view the right way to do things is to lie and spin because those ways were successful, so they must be right. These are the people who ignore all experts unless they happen to agree with them, remember.
Hence here we are with the Covid fiasco. What will be the next fiasco? The implementation of Brexit is the one we know, but what else could there be around the corner? It would have been the NHS, but maybe thanks to the side of the bus AND Covid that might just be too difficult, especially if Trump loses in November.
