Probably because you are at a senior level in that market. Few eu countries can compete with the uk in terms of pay and modern tech.

Working in Berlin tech, I found London salaries not that interesting considering the cost of living is easily 2x of Berlin.

That is when you manage to find a flat to rent in Berlin after queueing with 100 other people?

Well to be honest london is not an ideal place to live in. But thanks to remote contracting and london rates, the uk market can be quite attractive.

The money in London is in contracting.

If you have a family it’s probably 4x. 65-70K in Berlin are roughly equivalent to 200K in London.

Standard contract rate in London is ~500GBP per day, which is incredibly high compared to most of Europe.

62.50 GBP = 75.7 USD per hour is “incredibly high”…?

Yes. If your country does not have one of the tech companies mentioned in the article then $75 per hour is a fever dream.
