To answer the op's question, no, I don't think they would starve to death, but life would be very hard. However, maybe some of them should consider whether they can afford to have a(nother) child, if they are on limited income. I know that jobs may be lost at any time, but the man who was interviewed on ITV news earlier, said that he had been unable to get work for the last 5 years. He was then seen walking away pushing a young child in a buggy. Perhaps they should have delayed adding to the family until they could afford to do so?
