Paying for the privilege of being female

Today's news cycle contains a story about how most people (read: men) won't have enough superannuation in retirement to keep them in the lifestyle to which they have become accustomed.
The academic report also found that women have roughly half of what men have in superannuation at their time of their retirement (this part isn't news by the way, I can only assume because men have been found not to have as much super as they thought, this latest study is considered news).
I can't help but relate to this story because for the past four years, I have been the primary carer of our two kids, and haven't made any super contributions in that time. Why? Because I am self employed and I need to spend the money I make on our immediate needs. I accept fully that this is my decision. I have decided to forgo working full time, being stuck in traffic, being an absent parent - physically and emotionally, for a lifestyle which means our family earns less, but which I feel happier with for the time being.
It really sticks in my craw, though, when I read stories like this in which we're on the one hand expected to do our duty (thanks Peter fucktard Costello) to the country by having kids (which entails at least some time out of the work force, if only for the period of the labour), and yet we're also expected to pay our way in retirement.
Oh, and by the way, when you are lazing on your fat arses having those nation-saving kids, ladies, how could you possibly be expected to be paid for that time so that you maintain your financial status while you're lying back and thinking of Australia?
And if you are working anyway, don't even think about getting equal pay for equal work. I don't understand why more of a fuss isn't made of these insidious inequalities in our society. There was a Productivity Commission into paid maternity leave which found that there ought to be a paid parental leave scheme but then the GFC happened and now women's human rights don't seem to matter anymore. Again. When will the legislators in this stupid country realise this is not a gender issue, it's an issue for the whole of society and everyone benefits from the security and stability of a woman's livelihood whether or not she bears children?
