Ahh, a Daily Fail reader? That is just not true! There is a £20,000 fine per person for allowing a foreign national here without permission to work. It is not as prevalent as the right wing press would have you believe. There are more than enough British drug barons in the UK, I really don't think that A. asylum seekers has the money to start that and B. They would need support to do it.
We are constantly told that migrants are killing this country. That is bull! But if you believe any illegal should be sent back, what about Mo Farrah? He came here illegally. There are plenty of doctors and nurses who came here illegally originally, but without "foreigners", the NHS would collapse. We are an aging population, we need young people to come here. We threw out (effectively) those from Eastern Europe, so now we have to import from the Asian sub continent.
Migrants are not the problem, the right wing press and the government who learned that dividing us suited their needs!
