I was reading a book last night - "The War between the State and the Family" - in which it points out that for most people in work and paying taxes, having children is something that you put off until you can afford them. If you're on benefits, these considerations apply (if at all) with less impact, because you know that someone else will be paying for your children.
Indeed, the benefits system allows (if not encourages) men to impregnate as many women as they wish, without fear that they will in any way be responsible for their upbringing.
These discussion boards are full of evidence for this, with countless men being berated and insulted (often, no doubt, rightly) for having shirked their responsibilities and moved on to get another woman pregnant and so on....
Furthermore, we have somehow skewed things such that some couples actually pretend to live apart, as it is in their financial interests to do so.
Every change to the benefits system, from the 1970s onwards, because of its well-intentioned 'focus on the most needy', has had the unintended consequence of making it less likely that couple will stay together and more likely that children will be raised by one parent.
The most insidious consequence of the benefits culture is the way in which it encourages people to accentuate their apparent 'need' or 'entitlement' and, more to the point, instills fear in those that worry that "their benefits" will be taken away.
Gordon Brown's gradual ratcheting of benefits entitlement up the income scale (through tax credits) means that people who only a few years ago would have made do with their own earnings, now fear this loss.
I actually consider the benefits culture of this country, currently shaped, to be akin to abuse, in so far as it raises people's expectations unreasonably and slowly wears down any sense of pride they might have had for standing on their own two feet.
When we read of communities where there are 2, perhaps 3 generations of people who have not had a job, we should hang our heads in shame. The benefits system we have developed is allowing/encouraging people to procreate that, were it not there, would be unable to afford to do so.
Better a childless or 1 child family that supports itself than a 2/3/4 child one that needs benefits to stay afloat.
