Mid level companies have wide ranging talent since they almost by definition pay below market for talent, and don't even enjoy the brand value draw of the top companies. These companies benefit from the fact that there is some lag in labor discovering their true market value.

>Second, at high level companies, there's lots of European talent

Lots is subjective. The problem is the scale. You can easily hire 100 great devs in London over some period of time. 10000? Maybe not. It would take you too long to pick them up.
