immigrants enrich our country, ok lets do the maths,
100 immigrants bring over (not sure on the limit to dependants that a worker can have, there doesn't seem to be one) let's say 7 family members each = 800 so we have 100 skilled workers and 700 family members
for convenience lets say, each workers family consists of 2 kids and 2 pensioners and 2 aunts/uncles, mothers and or fathers of worker and his spouse.
so for every 100,000 skilled workers we have 700,000 unskilled workers, this seems a very significant number of unskilled labour, now these 700,000 unskilled workers have children too, not the pensioners but the children now the 200,000 children get married have children lets say 2 again that's another 400,000, aunts and uncles marry too and have 2 kids each thats another 400,000, so we have potentially unskilled workers within the first generation 1,500,000
so in 16 years we will have 100,000 workers 1,500,000 unskilled workers (are there university places available for these new British immigrants), lets say 100,000 new workers come in each year so 16 x 1,500,000 = 24,00,000 seems a bit high so lets halve it 12,000,000 this is a not too unreasonable assumption of the results of immigration on population growth. Factor in another 2,000,000 illegals and 10,000,000 asylum seekers and their families, then you have a very significant number 24,000,000 added to the population, of which 1,600,000 are workers.
this is just a simple understanding of immigration other variables come into this, i.e. the number. of dependants is not known, people lose their jobs and go home, but not very many.
