"You certainly can't go around carting people's kids off into care though, and anyone who thinks you can or should is heading for a social apocalypse where the poor have no rights."
Why ever not, kvalidir? The State has a duty to protect vulnerable children. It is not too much of a stretch to conclude that children sired in such a way as this are vulnerable, have little in the way of life chances and need removing from the circumstances in which they find themselves. If the State is to support these children it should be for the State to say just what form that support takes. It's no good fannying around with these people because they will continue to take the pi55. Simply doling out bucketloads of dosh to them does not work and something radically different needs to be done.
You mention the poor. These people are not poor. They have an income of around £41k a year (net, equivalent to about £54k before tax), and have had more than half a million pounds pass through their hands. Anybody earning £54k would be considered quite comfortably off. We're not talking about clobbering poor couples struggling to bring up a couple of children here. We're talking about curbing the pathetically irresponsible lifestyles of people who simply will not behave in a manner acceptable to the vast majority of the population who are paying for their fecklessness.
