They come here because it benefits themselves and we let them in because it benefits them as well as us. It means the vacancies in menial jobs are taken up, the economy is stimulated. When we let people in, it is because it helps us. Having more people here is not a bad thing, only 10% of the land in the UK is used for living on, the rest is green land, so we're not closed to being 'full', not by a long shot. Immigration is great, I want to work abroad at some point, only by immigration is this possible. There should not be a limit on who can live where, why should there be? It's preposterous, it's a world, why are we tied down to somewhere because we were born there? It makes no sense. Invisible barriers drawn by cartographers millenia ago.
