Thanks for looking into that - that claim also surprises me!

It makes sense to subtract the taxes for a comparison between pension and salary, but by taking investments into account, and probably living expenses too, since they depend upon investments, I think you're doing too much work to support that claim.

Presumably it is fairly standard for the average retiree to have more assets/investments than the average worker. Those assets generate income (or reduce living expenses). I think that is too different from the claim that the pension is higher.
