I've had a bit of a lightbulb moment ...
Our schools here are categorised into 'deciles', and it's a socio-economic calculation directly based on the families in the school community's incomes. It's adjusted regularly.
Decile 10 schools get the least government funding, and decile 1 schools get the most.
The upshot is that the higher decile schools have to fundraise like crazy to get resources for their school.
Guess who this load inevitably falls to... Yes, mothers.
There are constant (and I mean, constant) calls to join the school fundraising committee, to contribute to ad hoc tasks, to dedicate time (and money, of course), and yes, to flipping bake.
I hadn't really thought about it before, but this system impacts, and relies, far more on women than it does on men. Women feel far more guilted obligated to sign up for this sort of thing than men ever do. It's yet another way that leisure time is sucked away from women.
Our school decile system is actually not just a socio-economic issue (high decile schools out-perform low decile schools, at least taking the aggregated view), but it's also a feminist issue.
