circle of life


i saw this sketch on rory bremner show, bremner, bird and fortune
they were saying how useful polish people were in UK
but wha they fail to show was the circularity, the bigger picture
according tot he show some 400,000 polish people in UK,  70% between 20-34 of age
and only 678 on welfare
but what they fail to understand what happens when they get older, or start having kids,
something which even the government never thought about when they accepted emigrants from asia (india, pakistan), west indies etc..
