Can you elaborate? Why is it wrong to base individual pensions payments on individual contributions? I'm not following.

Are you just saying it wrong to lump people into two different groups arbitrarily? Like we don't base social payments on two arbitrary cohorts like "people over/under 68 inches of height", so why would we base it on gender?

The original poster was implying that other inequalities wrt gender "balanced out" the equality wrt pensions and lifespan. I was rejecting arbitrarily linking two unrelated things (problems), and consider them as cancelling each other out.

The poster also stated "In Finland this is solved by it not being possible to avoid state pension" so this isn't basing individual pensions on individual contributions, because much like life insurance, and individual pension would adjust for life-expectancy, whereas I believe the Finnish system is a flat rate wrt gender (this is what I inferred?).

The point about arbitrary groupings is a good one, but it will fall on deaf ears in places like the US, where established groupings have high political importance.
