Thanks for posting...
A couple of points. I agree with OAP, the whole increasing longevity thing is a little "rose-tinted". At the moment, with a childhood obesity epidemic in many western countries (esp the UK) longevity went down in 2018. Sure the tech will improve, but will it always be state-funded?
And I also utterly agree with Danny...the whole NI thing is just a ponzi scheme, always has been, always will be (until it eventually collapses). Whilst there are many macro economists who dispute the "technical labelling" of "ponzi" (preferring "tunnel scheme" or some such), there are few who would disagree with the basic premise (and the dangers thereof).
So yeah, in the very long term we are up sh1t creek in a barbed wire canoe, and pensions are only part of it...the NHS and care of the elderly are just as big and potentially more immediate.
And philosophically speaking why should any of this surprise us? Do we not read our history? Once a population becomes complacent and ever-more reliant and "entitled" to all the state is willing to provide it is already on the downhill slope.
The Romans discovered just that a few thousand years ago.
