We've done this to death in the earlier question, pastafreak (not sure if you took part as there were about 170 responses). However, your assertion that
"Those immigrants had been in this country as long as 12 and 17 years...and were working in most cases. I think your point is irrelevant. "
Only covers part of the point. It is true that many of those featured hd been in the UK a long time and it is equally true that some (though I'm not sure if "most" is correct) of them were working. However, the main thrust of the programme was to highlight the enormous sums they had been receiving in the form of Housing Benefit and the efforts being made to reduce the bill. In one case one of the subjects was working and earning around £150 pw. But he had nine children, almost all of whom had been born since he began placing such a huge burden on the taxpayer, and was enjoying a net income (including his HB) of over £800pw. So redvanman's point is not entirely irrelevant and it is no use saying "look how little they have left after rent". The whole point is that huge sums are being paid out to house people whose net contribution has been, and is very likely to remain, well below zero.
