BSC, I'm not sure about high earners receiving cb so they can feel they still have an investment in society - just 'all who have children, mind you!' and are getting something out of it, otherwise benefits will just go to the 'incompetent and feckless'.
So what about those who chose not to have children. If the above argument holds, should I feel disgruntled because I'm getting much less for my 'investment in society'?
As it happens, I'm very happy for my taxes to be spent on all your children, to be born in hospital, go to school, get medical care etc. I got all those things as a child myself. However, as I'm going to be on my tod in my old age after saving the government a packet by not having kids, it would be nice to know I'll get some help when I start getting a bit decrepit as I'll have no children to help me access the services that are left, cart me around the place, make sure I'm being fed etc. Yes, those services are theoretically there, but having helped my elderly mum and watching my cousin sort out care for her mother with dementia, I am getting slightly worried now about how I'm going to manage when I'm completely alone.
It's also been interesting since I've been on MN to see how some families manage their money. My DH and I earn the same and have no kids, so it's the obvious thing for us to have our own money we can spend on what we like, and contribute an equal amount to a joint account to pay all household bills. But if we had kids, it would be completely different.
But I'm amazed about the couples I've read about that continue to have 'my' money and 'your' money even after children come along - the husband earns 60K for example, the wife struggles on in a badly paid part time job or is completely SAH in order to look after THEIR children, yet they continue to pay equal amounts of their wages into the communal pot, with the result that the wife is near penniless, whereas the husband has plenty of extra money for trips away, hobbies and gadgets. Then when cb is taken away from couples like this, the wife is in trouble because it's seen as 'her' money and she is the loser. The husband in these families feels under no compulsion to make up the difference in the family budget from his high wage.
CB was brought in at a time when society was more unequal, so a deliberate decision was made to pay it to the mother because it was felt much more likely that she would spend it on the children, and she would be guaranteed to have some money she could call her own. It seems some wives of high earning husbands are still having to rely on cb to manage because their husbands don't see looking after children as a proper job, and think all the money they earn belongs to them to do with as they wish, not to look foremost at the needs of their family unit. So it perhaps some husbands' sense of entitlement to what should be joint resources needs to be addressed.
