Australia transitioned away from defined benefit schemes in the eighties and early nineties, and has increased retirement age (not a legal concept here, but when you can access a pension or your benefits) has been increasing too, from 55 when I was young to 67 currently.

I'm not a huge fan of the resulting system in its details, but it's a sign that people and politicians used to care about longer-term thinking. (Interestingly, these reforms were from the Left, not Right, which maybe explains why they happened?).
