Not the person you asked, but for me:
- In 2017 I lost my £70,000/yr dream job as the company I worked at decided they couldn't keep their EMEA campus in a country that hasn't decided how, when or even if they were going to allow foreigners in.
- I had to move to a shithole town in Nottinghamshire to live by myself in a cramped one-bedroom flat to do a job I hated for £22,000/yr.
- That company went under because we couldn't import the network equipment into the UK because of Brexit. Most vendors weren't bothering since there were shortages anyway, so why not just send all their stock to Germany where there's no nasty surprises and plenty of buyers waiting.
- Ended up doing minimum-wage shift work at an Amazon warehouse and Deliveroo deliveries to survive.
- Got another, similar job on £20,000/yr.
- Not had a holiday in six years. I used to have at least two a year.
- Can't get a CPAP machine for my apnoea because of difficulty importing them (ended up getting a friend in France to buy one for me).
- Local supermarkets still can't get a lot of fresh fruit that they used to stock. Empty shelves common.
- My savings went from £50,000 to zero.
- Government is pissing money away on detention centres and hotels for immigrants because they refuse to cooperate with the EU.
- Government is also planning on ripping up our Human Rights (ostensibly to deal with the immigrants) and has even indicated they would like to abolish GDPR, bringing it full circle to OP's comment.
So, yeah. Not everyone has had as bad a time as me, but everyone I know has encountered some negative fallout. I've yet to encounter anyone who has actually benefitted, even indirectly.
This begs the question: tldr. Im going to fridge an egg and eat it raw but cold.
