Welfare Reform Bill

Is not the really big change that we are discussing the fact that when the CSA was first established, the maintenance moneys went to the Treasury to offset what taxpayers were putting up because, generally speaking, fathers were not prepared to do so, whereas now that money remains with the family? Is it not reasonable, in such circumstances, if people are going to get a top-up to their benefit that they should contribute to the cost of gaining that extra money? On the timing, should we not charge people once they are getting the money, not before?
