QALY Me Maybe?
MacKenzie Scott's Giving, in Quality-Adjusted Life Years (QALYs)
Fans cheer, skeptics squint, and the comments turn one billionaire giveaway into a moral cage match
TLDR: A new model says MacKenzie Scott’s $26 billion in donations may have created roughly 70,000 to 200,000 extra years of healthier life, but even its creator stresses that’s a rough estimate. Commenters quickly turned it into a bigger fight over whether the math misses education and dignity — or whether taking money away from billionaires is the real victory.
A wonky new QALY model tries to answer a deceptively simple question: what did MacKenzie Scott’s $26 billion-plus giving spree actually buy in human wellbeing? Depending on how trusting you are of the research behind it, the answer swings wildly — from about 70,000 to 200,000 quality-adjusted life years, a health measure that tries to combine longer life and better life into one number. But in the comments, the spreadsheets were almost beside the point. The real action was a full-on argument about whether this is careful math, unfairly narrow bean-counting, or proof that Scott has become the internet’s favorite anti-oligarch.
One camp thought the model felt too pessimistic, especially because a lot of Scott’s money goes toward children, education, and long-term opportunity — things that may not show up neatly in a health score today but could echo for decades. Another camp went full emotional: one commenter said just knowing a billionaire like Scott exists has boosted their own quality of life, which is either deeply sincere or the most wholesome plot twist on the internet this week. Then came the sharpest hot take of all: even if the donations were inefficient, draining billions from the ultra-rich is itself a social good because it leaves less cash to buy politicians and media outlets. Oof.
The biggest joke hiding in plain sight? A model meant to measure health sparked a comment section obsessed with morality, power, and billionaire vibes. In other words: classic internet — come for the math, stay for the existential class war.
Key Points
- •The article estimates the QALY impact of MacKenzie Scott’s philanthropy, covering more than $26 billion in giving since 2019 and citing $26.3 billion through 2025.
- •It identifies the main uncertainty as the model’s evidence stance, which produces outcomes ranging from roughly 70,000 to 200,000 QALYs.
- •The model uses 13 intervention archetypes and relies where possible on published causal estimates for cost-per-QALY assumptions.
- •Effects are discounted toward zero according to the strength of causal identification, and results are simulated through thousands of Monte Carlo draws.
- •The author says the figures are model outputs rather than measured facts and notes that the code, tests, and sources are published on GitHub, with a TypeScript implementation running in the browser.
