Just read the article in the G&M about the percentage of pre retirement income required in retirement. I don't know if I am getting more cynical with old age or if I just have more time to think about this stuff, but it seems to me that these commentators continually confuse correlation with causation. It's not that retirees only need X% of pre retirement income but rather that's all they have so they adjust their budgets accordingly. My take away is "save as much as you can(within reason) and then spend as much as allowed by the accumulated nest egg". It turns out that due to luck and perhaps good planning we are spending about 30% more in retirement than before. This is because we can. Acknowledge that we are not typical but the stuff you read seems pretty poor to me. Any thoughts?
