Once, when I was a day care lady, my DH and I took the 7 day care kids and our own two for a day out in the city. They were all staggered ages and did look like one family, and we were both shocked and amused at the quiet remarks made by people passing us by, such as 'Why don't you try watching telly at night, for a change?".
As for the family with loads of kids, I admire them for doing exactly what feels right to them. They finance their family through their own business, and the children will be learning to do their share in the house, look after each other, and grow up with a sense of responsibility. As for the cost of their education and health etc: these costs exist for all kids regardless of family size.
I think there is a lot of negativity in society about benefits, but I'm all in favour of ensuring everyone has enough to live on, even if the state has to provide it. Without these safety nets we would have utter misery and much more crime, abject poverty and many more children living in deprivation, hunger, and bad health. Benefits keep the money circulating which keeps businesses going, thus helping the economy. The tabloids search around for benefit cheats, and then do lurid stores about them. Also, we all remember nasties like Karen Matthews. But these are not the norm.
