I'll answer your question as best i can, 74. I look at some of the photos, there's one this morning of a Syrian lady in the sea desperately trying to hold a baby above the water, and I know that on a human, individual level I would have to help.
An accident of birth has put me in a relatively affluent, safe environment, and to those much has been given, much should be expected. Immigration can bring net benefit to a country in any case, so it can be argued that economically we are acting in our own self interest by accepting people into the country.
To me its also obvious that a lot of our infrastructure is creaking under the strain of austerity, so those who say that housing, health service is already overburdened are right, have a point, and shouldn't be dismissed as overly selfish, racist, or blinkered to the genuine suffering of others. This reaction makes that debate harder to have, and practicalities dictate that if as a country we are going to experience population growth, we have to plan successfully for how to accommodate it. If this came from people already in the country having more children and living longer purely, we would have to do something, why do we think "indigenous" people have lives of greater value than anyone else?
When people say "we first have to look after our own", I agree with them. I just define "our own" differently, to include all human life. And yes, there will be some trying to enter the country who are horrid, mean, radicalised, takers not givers...they are people, and like every community, there are good and less good. That is no reason to lump all people as one.
Thats the principle. In terms of action, I think we are behaving dreadfully, we need to accept people into the country with a plan to help them contribute to society and build the life they want...radical, forward thinking plan, not the current wishy washy hope the problem will go away...it could be an opportunity for the country if used correctly, and, going back to the start of this rant, as people it makes us human...I don't think anyone on this site could see suffering directly in front of them, such as the lady trying to save her baby, or the other iconic photo of a Dad with his family on a sinking dinghy and not want to help...why should we not expect our country to do the same?
