The Education Ministry's Adult Literacy and Life Skills survey found women who were highly skilled at maths and reading earned at least $18,000 less than their male counterparts on average.
Salaries for women with high literacy and numeracy skills ranged between $39,000 and $46,000 on average, while men received between $57,000 and $75,000.
Men in the lowest skilled bracket earned between $24,001 and $30,000, while women received $10,001 to $17,000.
The article doesn't seem to quite make the connection between the gap and the possibility of a whole heap of subtle sexism, so let's make it for them.
The evidence here is that women are paid less even when they have the same skill level as men. To my way of thinking this can only partly be explained away by the whole "women take more time out because of their biological urge to breed" argument. Low-paid (not necessarily low-skilled) occupations are dominated by women, not because they have uteruses and sometimes like to fill them, but because women's work has been undervalued for eons - not just the work of individual women who are underpaid, but also the lack of recognition of the positive contribution that traditional "women's work" makes to our society.
