1. We could increase global GDP by 67pc to 147pc. This means we could more than double global wealth.

2. Immigrants create jobs, they don't steal them, because there is not a fixed pool of employment.

3. They contribute more in taxes than they cost in services or welfare. In the U.K., they contribute more than natives.

4. They'll also be vital to the future, as immigration has massive potential to help offset government debt.

5. Immigrants are incredibly entrepreneurial, with more than half of the silicon valley tech businesses having an immigrant as a key founder, and in the U.K. 17pc of immigrants set up their own businesses.

6. Immigrants send home more money to the developing world than we do in aid. (About 3x as much).

7. A seasonal migration programme in New Zealand was more effective at alleviating poverty in developing countries - by giving entrepreneurs experience - than any other method.

8. Since the year 2000, 40,000 people have died trying to migrate in unsafe conditions due to criminalisation.

9. The public wildly underestimates, at least in the U.K., the extent of immigration we already have. The public thinks immigrants make up 31pc of the population, when it is really 13pc. They also think Muslims make up 25pc, but the reality is that Muslims comprise about 5pc.

DEY TOOK HIS JUUUUB

DEY TOOK ER JERBS!!

Let's open our borders and let all who want in, to come in. They don't have to learn our language, our laws and let's give them a head start compared to natives. Oh and since they are not being screened, they can bring whatever disease they are carrying with them. From the polio to ebola and beyond!
