I spent 10 years working on sister units to those turbines, and it seems some things are common.
Girls in year 11/12, planning (not hoping, but scheming) to "snag" a coal miner footballer as a trophy husband, not worrying about schooling and where's the money going to come from, as the mines paid.
Would hear them while they worked at the local supermarkets as checkout girls, telling their co-workers that they hoped to be pregnant by Christmas.
It was unreal to move here, and see the culture.
Miners weren't moving away, due to the money, and the qualifications that they needed to get it (they can have that job, 12 hours underground, you couldn't pay me enough), girls didn't aspire to move away (or if they did, they moved way away as professionals, Drs etc).
A lot of the entrapment ended up in domestic violence and divorce.
Free contraception would have done nothing to the culture, as the view was to "settle down".
As we became closer to the big smoke,and property prices rose, more and more of the women were forced into work, and having fewer children...
And the Baby bonus kicked in, $5k for having a kid...$5k was more than most of these girls had ever seen...so guess what ?
A mate with a Doctorate in Philosophy once stated that he saw an agenda to create population, cannon fodder, and make them feel happy about their "opportunities"
