After FDR's death, she chaired the UN commission that drafted the Universal Declaration of Human Rights, which says economic security is a human right. That's the idea we carry forward: an economy should give everyone real security and a say in the decisions that shape their lives.

We really need to make Meng's Big Data Paradox central to teaching, don't we? Researchers don't know this stuff bc they have never been exposed to it. But it is fundamental. (Link to paper PDF statistics.fas.harvard.edu/sites/g/file...)
3. Compensating for quality with quantity is a doomed game.
3.1. A law of large populations? Under a probabilistic sampling, a central
driving force for the stochastic behaviors of the sample mean (and alike) is the
sample size n. This is the case for the Law of Large Numbers (LLN) and for the
Central Limit Theorem (CLT), two pillars of theoretical statistics, and of much of
applied statistics because we rely on LLN and CLT to build intuitions, heuristic
arguments, or even models. However, identity (2.3) implies that once we lose control of probabilistic sampling, then the driving force behind the estimation error is
no longer the sample size n, but rather the population size N. Specifically, (2.3)
and (2.5) together imply that
(3.1) Zn,N ≡ Gn − GN
