I'm from EU and would be totally open to move to UK if there was an opportunity to make more there while working on something cool. But there simply isn't?
Then there are US startups where I could likely make 2 or 3x what I make in EU or UK.
So why would talent every consider moving to the UK to build a startup in 2025 anyway?
A lot of people choose to start businesses near their friends or families.
Doing soldering of prototypes? Good luck finding a landlord that would let you do it. The moment they hear "fumes" is a nope, fire hazard, safety risk and won't let you...
Not sure if it's true so let's look at some stats: Germany median for software engineer: €66,000 United kingdom median: €58,000
Note depending on source, these numbers both vary broadly within the same range, but with Germany salaries being about 10-15% higher on most sources, so nowhere near the figure claimed.
EDIT: Please don't downvote me for admitting a mistake
33% less equates to them earning roughly 50% more. The difference between 10-15% and 50% is huge!
(trivial example, if someone is earning £100,000, then someone earning 33% less makes £66,666. But Someone earning £100,000 makes 50% more than someone making £66,666)
