Ok well I'll bite, not sure everyone one here is open to respectful honest debate, but I'll say it anyway.
Clearly the OP is disingenuous, OP is looking for an excuse to complain that Brexit has made their job more difficult and express the contempt they feel for those responsible.
I voted for Brexit for many, many reasons, never did I expect it to be an easy transition. Wage suppression will take some time to rectify itself. Had the EU been willing to compromise on a few things we wouldn't have any reason to leave, their one size fits all policy of all countries having to abide by the same rules might work better for those actually on the continent, but we are an island and have issues that are unique to us.
It's hard to really tell what the benefits will be because we're still paying the EU for various reasons so haven't seen any financial benefits to date. Plus the war, fuel prices, pandemic etc. are making it hard to pinpoint exactly what affect Brexit has had.
I always knew we would have a period of instability and adjustment, before we saw any real benefit. I voted for it anyway because hopefully my kid will benefit from increased wages, more and therefore lower (comparatively) priced housing in the long run. It was never about instant gratification.
The incredibly slow reaction from the EU regarding the pandemic, vaccines, etc., does highlight what an inefficient and complicated system they have with regards to decision making.
I could go on about allowing countries to join who don't meet the criteria and how destabilising that is to the economic EU bubble, but it's boring and complicated and I did my research but really I cba setting it out here to be disparaged and criticized for it.
Am I sure I made the right decision, no not 100 % did I weigh up the pros and cons and come to an educated guess, yes I did and I have no regrets so far. Yes my arse is twitching but nothing worth having ever came easy. Hate me if you want, but the main players in the EU France and Germany clearly hold grudges against the UK and we weren't treated very well considering how much we contributed to the pot.
The EU has its own problems that it needs to address too.
It may take twenty years to see the true benefit or deficit of Brexit, but if everyone got behind it and made the best of it we might get there quicker than squabbling over something that's already been done.
