Brexit is annoying for consumers (try buying stuff from Germany as easily now) and actively lethal for some businesses. I'm feeling the sovereignty already
More annoying than that. Try hiring software engineers. When I started working in London 15 years ago my colleagues were from a mixture of counties across the EU, easily greater than 50%. Now it's rare to see a CV from outside the UK except for a perhaps people from India.
So? What's your issue working with British and/or Indian people?
European talent is more than nice to have access to.
There's no problem with them. The problem for UK is that the other people who could have worked in the UK and produce value in the country, have left and now contribute to other countries' economy.
What's wrong with that?
What's wrong with losing access to a giant talent pool of hundreds of millions of people who can move immediately, visa free?
