From the time when I used to live in UK - You guys have almost no manufacturing and no tech sector. You are importing everything from abroad, yet there is nothing interesting in UK, no reason why I should ever want to get a work visa into the UK. Only thing which works is finance services, but you completely forget on that one during Brexit and you were concentrated on fishing which has almost comically low fraction of UK's GDP. So even the financial sector is slowly pouring away into USA and EU.

Despite your dire situation, you are keeping to make things even worse - See UKCA mark, return of imperial units, endless squabble with EU over Northern Ireland Protocol and threating a trade war, which would finish you off.

Thing is that you used to be interesting for investors (and for me personally) because you were country speaking English and connected to EU. So if somebody from abroad (USA, Asia) wanted to do a bossiness in EU, he would start in UK. That's gone thanks to Brexit and Estonia + Netherland took this role from you. Now you just become a hollow English speaking island which really has nothing to offer.
