Unfortunately we are paying for a lot more than just him.
Due to our very lax immigration (from all parties over the last 30 years) and our generous benefits system we are paying for hundreds of thousdands of people like him to live off benefits.
Why do you think many immigrants and asylum seekers pass through so many other countries to get here, because word of our easy-to-abuse benefits system has spread all over the world.
We really are the most gullible country in the world, we will ltake anybody, and let them live of us without contributing anything.
