I agree it's not rocket science.
Of course those from poorer countries than ours (most of the EU) will come here looking for work and whatever other economic advantages there are to be had.
Remember also that 'seeking economic advantage' (or suspicion of doing so) is the main reason we and our loved ones from the Philippines have to jump through all the hoops and pay extortionate prices for visas.
There is so much unfairness with the current situation as far as WE are concerned.
Also, it may be fine and wonderful for all these EU migrants coming here to fill all the job vacancies, but what about OUR children. What about all our teenagers about to leave school or college ?
They are being deprived of their 'birthright'. Where are they going to live ? Will they feel obliged to leave THIS country, their home, to find work ?
Their parents and grandparents are being deprived of an NHS and other services that they paid into for maybe 50 years, and also being asked to put up with other overstretched services and infrastructure.
What have they done to deserve this ? Did they vote for this ?
