Try looking at the issue from a females perspective. The birth rate rate is now down to 1.6. Women that are having children are now deferring that until they in their thirties. Remember Costello preaching to women to have 3 children ? One extra for Australia?
Why on earth would they, in this economic climate? Why would they even bother getting married and having a family ? I know many women who say - nup, thanks anyway. Gender equality ? Where ?
