It is a bit more complicated than that and I feel extremely ambivalent about it.
Voters were promised the open market and trade of goods would remain and that a good trade deal with the EU would be easy to negotiate. This did not happen, could never have happened, but it was what they were told. If Brexit was a product bought in a shop you would be able to return it: Not fit for purpose and not as advertised.
The UK press and TV had been maligning and downright lying about the EU for decades. Remember the sausages, the bananas, the pillows, the unelected officials… They made the EU a huge boogyman that only existed to harm the poor ickle UK. And they swallowed it line, hook, and sinker.
That paved the way for the Brexit poisonous messages, it made it impossible for sense and truth to even be mentioned. Remember both major parties supported Brexit!!
I have many friends in the UK (quite of few of whom made it to the EU in time…) and I feel no joy in it, but this is what they elected, chose to do. Yes, they were lied to but ignorance is a choice in this time and age. There were voices of reason, hell Merkel squandered some good political capital to buy the UK two extension based on some very creative reading of EU regulations and still they malign her.
So on one hand, meh. Pave over Kent, reap what you sowed and good luck with it.
On the other hand, an enormous loss. I have seen good people lose jobs over this, careers broken up, marriages lost, friendship shattered. There are businesses going to fall over right where I live. Costs of simple things will go up, travel to the UK once a simple boat ride will now be a huge pain, all for some stupid political games to line some pockets of rich people… buggrit.
