I’ve explained pretty meticulously in the past how it’s made things worse across multiple sectors, so I doubt anything I say now will make any difference.
I’ll give you one fun fact that I haven’t seen anybody mention in the media though: due to post-Brexit rules regarding how long EU tour buses can stay in the UK for, in some cases the drivers are having to catch a ferry to Ireland or France just so they can turn around and come straight back in again. Often this requires factoring in an entire day off due to the time it takes, which costs thousands of pounds because as well as there not being any show to monetise that night, all of the bands and crew members require hotels. That goes on your ticket price. There aren’t enough UK-based buses and drivers to fill demand, which in the case of the drivers themselves (as well as many riggers and stage hands) is partly because a lot of them moved to Germany so as not to lock themselves out of the majority of their work once Brexit kicked in.
Numerous merchandise companies have also slashed their UK operations and moved the bulk of their fulfilment to places like Leipzig, because the EU makes up far more of their business than the UK and getting items on/off this island is now far more difficult and costly. UK merch printing companies have also seen their business more than halve in some cases, as touring artists are using EU companies to make huge swathes of their garments as they can pass freely through European borders without needing a carnet, as they were made in the single market. Previously the UK companies would print the lot - now they print the stuff for the UK shows only and nothing else. If they print any of them here at all. Because they’re printing less units, the bulk discount has shrunk which means the price per unit is up, which means the consumer pays more. Again.
I’m going on tour myself next year across Europe as well as the US, Japan and Australia, which now requires me applying and paying for working visas to enter places that previously I could’ve strolled into by nonchalantly flashing my passport. I can’t put my rates up because otherwise an EU citizen will get the job over me, so I have to swallow all the costs myself. I’ve had to take a real terms pay cut while spending more time working.
And that’s just the stuff I can be arsed to type.
