I actually work for the CSA and get many different and varied opinions, not many I care about really as its my job and I actually like it BUT yes, both sets of parents should pay for their child. And believe me, there are many women who leave their kids too, its not just men! I particularly enjoy calling up the real assholes tho, eg, I had a lady who had had an affair with a married man, got preggers (not on purpose) and he dumped her. As she was on benefit, she was a compulsory client so HAD to come to us, as is the law. I contacted the "father" and he said his wife didnt know about the affair, let alone the baby and that I, ME, would be responsible for causing a divorce if I pursued the claim. I had a certain amount of pleasure in saying "Its not me who causes your divorce, it was you the moment you took off your trousers, Sir". Lol. He was a little gobsmacked but he'd been giving me shit for the entire call!! Dont get me wrong, the mother was morally wrong too but I'm not their to judge her, just to get cash to the child!!
