This is much talked about but so far I've only been seeing the opposite. Since brexit, the UK has so far banned fish trawling in the North sea, banned live export of animals, banned the import of fois gras, and created a much more environmentally friendly alternative to the EU's (absolutely atrocious) common agricultural policy.
> lowering regulatory standards
I'd argue that not all regulation is good regulation, e.g. the GDPR
> Lowering taxes
This is could feasibly happen and you could say it already is by looking at the way the tories have further rigged the housing market and stamp duty post-covid. But I fail to see what that has to do with the EU really. I don't know a lot on this subject though.
> undoing workers' rights legislation
I can see this one happening sadly. Am I not right in saying though that a lot of workers rights come from the judiciary, not the government? Example: https://www.bbc.co.uk/news/business-56123668
Brexiteers would see tony martin as a hero.
(Is this another one of those issues where someone is in favour of Brexit because they think the EU prevents something that is nothing to do with them, because they've been lied to by the UK press again?)
Thankfully the armed police have very stringent training in the Uk.
What we can't have is pistols, apart from 20 or so people in the Olympic pistol shooting teams.
Do you know what does help keep the wealthy wealthy? A ready supply of cheap labour from outside the UK.
Many leading brexit proponents are rich people who made their money from the collapse of the soviet union and have assets largely outside the UK. One conspiracy theory is that they are attempting to crash the UK economy in order to buy the dip, make money from shorts and the sell off of state assets.
Another conspiracy theory is that brexit has an ideological basis in the idea of the soverign individual - related to the idea of the randian hero, the idea is that as states weaken in power, rich people will be able to transcend citizenship and attain some kind of libertarian utopia where they can do what ever they want. One of the leading brexiteers dad wrote a book about it which apparently has some following, but maybe people are just surprised that right wing politicians want a smaller state.
There is also an idea that the UK and its dependencies (e.g. virgin islands) are a tax haven. A lot of brexit money came from US activist billionaires and hedge funds, but a lot of it came from very rich russians who fled tot he UK in the 1990s with huge amounts of money that Russia say was stolen visa corruption and other criminality. The theory is that brexit was a response to EU money laundering and tax evasion rules that would have linked these rich criminals to their money to its sources, leaving them open to russian legal challenge. The theory is that for those people, brexit was a means to escape the net.
In my opinion, the role these factors played is probably overstated - brexit was primarily a backlash against globalisation and change, and a protest against the UK status quo by parts of the population that didn't believe they benefited enough from it, much like the election of Trump in the US.
