the best pension a young person can get these days is to have children, treat them well, and raise them to take care of you when your older.
In the scheme of history, pensions will be seen as a blip. they were a great thing that existed for a few generations, but quickly became outdated. They work great if you have a reasonably young population, with old people who don't live to long and plenty of people still relying on their family. But they are a nightmare for a society that has less and less young people, more and more older people living longer and as a result suffering more medical conditions, and less and less old people relying on their families, and depending on the state instead.
People act like the idea of old people reciving a pension is a fact of history though. Its not. Old people, when they couldn't work any longer but were still alive, were burdens and depedants on their younger family, and that's how it was for most of our history. The idea that old people can live, independant from their family, and in some cases remain just as wealthy and have just as much money as they had when they were still working, is a fleeting conception that's only existed in recent history, and seems like it will die out again soon.
It would help though if some retirees didn't take the piss. I know quite a few who will retire at 55, on the exact same wages(near enough) that they earned whilst working. They veiw this as an entirely normal state of affairs.. and think they are actually doing a good thing for the younger generations because they are not a burden on them! What they don't see is that their hoarding of wealth and assets that has lead to them being able to maintain their income, despite not generating any wealth or being productive at all, for 35+ years is part of the reason why the young now are the first generation in centuries to earn less then their parents and see a fall in home ownership..
For me and my wife we will take a mixed approach from both of our backgrounds, Asian and English.. we have our savings, investments and private pensions.. but we will also be heavily investing and relying on our children, in the Chinese tradition, and fully expect them to take care of us when we are older. Its a pay-off though because the balance to that is that parents in Chinese culture must give far more financial support and wealth when their children are younger, but expect far more back when they are older. No chance I will be relying on a state-pension though.. I doubt it will even exist in the 50 years until I am able to claim it.
