British are entitled for all Indian jobs

There was a lot of talk about change and hope when a new president came in one of the nations of the world. He was advocating a policy against foreign workers. This call is getting picked up in many nations like Australia, UK..................

I was just going through wiki and saw some interesting dates.

First settlers went to US in 1607.
It is now 2009.
Hmmm about 402 years.................
So this 402 years give the right to say to no more immigration.

First Afro-americans went to US in 1619.
That gives the president a history of maximum 390 years.
So this 390 years give the right to say to no more immigration.

First settlers went to Australia in 1788.
It is now 2009.
Hmmm about 221 years.................
So this 221 years give the right to say to no more immigration.

These lands where taken away from the original occupants and are now occupied by settlers, who say 'NO' to new settlers and outside workers.

Now another interesting fact.
The British came to India in 1617.
They were there till 1947.
That is about 330 years.
So are not the British entitled to all the jobs in India, hmm,,,,,,,,,,,,,,,at least half ................ or ..................

Still I am confused..................
