I didn’t read this piece fully or spend too long in the file, but passing on my feedback.
I found several parts unclear:
By “Traditional retirement age” do you mean “target retirement age?” if so, I’d revise the language accordingly. As of now it reads more like a fixed number than a variable to adjust, and aiming to retire early seems like a big part of FI from what I’ve seen, so would imagine varying it is the intent
Should I include my passive cash flow in my “annual income,” or do those get added together in the background (and hence would be 2x counted if included in income)?
I’d label rows 13-17 as “calculations” or “calculated fields” in Column A
Should I count savings “locked up” in retirement accounts in my portfolio value?
Is there a way to account for future Social Security benefits?
And I think a formula or two may be broken
Donations % seems to be using passive cash flow as the denominator, rather than income (or income + passive cash flow)?
“Years to FI” doesn’t seem to return a number of years but instead “You’re FI” or “You won’t hit FI.” And I don’t think “You’re FI” means I can retire now but instead is saying if I keep earning, saving, and spending at the same rate then I’m okay… which is not what I’d have expected it to mean?
There’s certainly been discussion of the potential efficacy of growth-focused interventions from an EA perspective, as in this Forum Post, “Growth and the case against randomista development” (a winner of the EA Forum First Decade Review!)
To give you a taste, some arguments of theirs I found quite thought-provoking were:
Take a hypothetical cost for all economists from 1960-2010 ($300B). Assume the only impact the entire field had in this time was to “increase by 4 percentage points the probability that the Chinese government shifted to [its] new economic strategy” which drove their growth 1977+. Then, this “intervention” (the field of economics) would still have had higher ROI than cash transfers (or a “Graduation Approach” program to helping lift people out of extreme poverty)
Charts showing the relationship between median income / consumption and extreme poverty which suggest the importance (necessity?) of high median income to the reduction or elimination of poverty
...I also believe they made an argument that health interventions are actually “cheaper” through Growth vs. direct interventions due to improved health outcomes we see in countries as they grow economically… though I’m not seeing that now as I re-skim so perhaps that was a different piece
All of this said… it’s hard to imagine this logic would hold (as) true for interventions in the US where Open Philanthropy is saying they’re focused within this fund at the moment. So on that front I’ll admit I’m more confused!
