Re: The elephant in the room - stagnant wages because of the free movement of labour

You made me laugh.
Oversimplifying things a bit here, but the reason IT jobs (like yours?) exist in the UK in the first place is because it combines two (three) attractive premises:
1. Ease of access to finance (London)
2. Ease of access to qualified labour (EU)
3. (Bonus) English is a dominant world language, making things easier for everyone involved.
If you remove #2, you will see businesses moving to places like Berlin or Silicon Valley. Capital may follow (it's easier to move capital than people).
So instead of getting a higher salary for exactly the same job, you're more likely to end up having to pull up stakes and move to Berlin, San Francisco, Prague, or Barcelona.
