NZ was one of the first countries to provide pensions for elders, and it happened in the early 1900s. It was largely because there seems to come a time when you cannot work any longer (disability), but you can live well enough for a few years anyway. People who couldn't work and weren't wealthy enough to support themselves for a bit caused particular social problems that exist due to poverty -- and NZ sought to abate that poverty (which is sort of the point of most of these social systems).
So, they created a system where people who were old and could not work would have housing, food, and medical care to abate the social and public health problems related to poverty. It wasn't about old people having leisure time in their 'golden years' so that they could go fishing or play lots of golf. It was so that, overall, the problem of poverty would be abated, and that these individuals would have a healthy, dignified end-of-life time.
And that, really, is the point of "retirement" in that "original-ish" form. Otherwise, you just worked until you couldn't work any longer and hoped that family took care of you or you were wealthy and knew that that wealth would take care of you.
I also love this concept of "golden handcuffs" because it's something that DH and I talk about a lot, as well as MMM for that matter. Using some MMM principles and planning out our lives going forward in the US, we have a clear path to returning to independent work (rather than necessarily working for companies).
Our desire is to work long term, ie "never retire" because we love our work. But, we want it to always be on our terms -- so the combination of living frugally, planning carefully, and saving well (plus fingers crossed everything going well) will allow us to do this, while also still earning income over time to add to our pile.
