(the downside of 20th century work on increasing life expectancy is that most of it happens in retirement, making pensions much more expensive)
edit: I have not done the maths, but I would not be surprised to discover that the total average pension paid to someone retiring at age 65 in 2026 was much more than the total average pension paid to someone retiring at age 65 in 1986, while at the same time the weekly amount of the earlier one would be higher. Because the more recent one has to spread the money over more years.
I think it depends on your financial literacy, I know a lot of people who have no idea how to invest their money, you would be surprised how many people would be more comfortable with someone else managing their life savings for them
Someone choosing to be illiterate and getting scammed out of their money still does not make sense. Life doesn’t get much easier than picking the target date fund with the year you expect to stop working.
