They are quick to refer to British expats, particularly in Spain for some reason, as if these may be compared to immigrants, both legal and illegal. This is not comparing like with like.
The majority of our expats are taking vast amounts of money into the Spanish economy.
They are happy to congregate together but do not require special treatment and insist that their hosts must change.
Spain is far from being overcrowded.
All of these Brits are are fully legal.
Even the younger expats are usually in work, often serving the British community. Many own businesses and pay taxes to Spain.
The UK loses through its immigration policy - Spain gains from its own version.
