Ruth,
"My point, Keith, is that "too much immigration" is always going to be relative to the resources and econonomic production within a particular society. If more people are productive, there are more resources for everyone."

I have argued that our very high population density and the serious concerns over immigration related issues are evidence that things have gone much too far.

"I would argue that tax-paying immigrants are not nearly as much of a drain on available resources as the indigenous Britons who do not work, and who live within the benefits sub-culture."

I absolutely agree Ruth.

"I know that this sounds incredibly reactionary, but I would really like to see this sector of society quantified in comparison to the "drain" on resources caused by immigration. I feel that it's easy to scapegoat the immigrant as the cause of Britain's problems, when in many cases, as highlighted by Don T, we are the solution."

I tend to agree with that, and certainly do not go in for scapegoating.
It is just a question of numbers.
