It didn't come up much during the presidential primary, but the fight over education reform is one of the biggest rifts in the Democratic Party. Simplifying somewhat, on the one side are leftists and teachers' unions, who favor traditional public education, teacher tenure, and generously funded schools. On the other are school reformers and a slew of billionaires, who favor stringent performance metrics for teachers and students, making it easier to hire and fire teachers, and privately-run charter schools.
Hence when John Oliver did a long segment on HBO about hideous mismanagement at some charter schools, the Center for Education Reform put out a $100,000 bounty for the best video response from an individual charter school.
It's an interesting debate — but the education reformers are missing some low-hanging fruit. Most research I've seen suggests that, on net, charters aren't that different from public schools. Some do better, a larger proportion do worse, and a larger proportion still do about the same. However, there is one simple and easy reform that would help American children, especially minority ones: Put a stop to lead poisoning. It turns out being poisoned with heavy metals is none too great for children's education — and a new study demonstrates that even very small amounts of lead poisoning can damage children's learning.

Lead was thought to be a solved problem for quite some time, since leaded gasoline and paint were both phased out in the 1990s. It has come back in view due to the water crisis in Flint, Michigan (which isn't remotely resolved, by the way) — but still in a limited way. That ongoing disaster rather makes it appear as though lead poisoning is mainly an issue for crumbling Rust Belt cities with severe economic problems.
This is not the case. As Julia Lurie points out, data collected by the Centers for Disease Control and Prevention shows that lead contamination is a serious issue all over the country. Only about half of states even report lead data from children's blood samples, but those that do show many counties with serious lead contamination — naturally those with high poverty and/or high minority populations.
And as a new NBER working paper demonstrates, even very small amounts of lead appear to have negative effects on children's education. The study looked at data from Rhode Island, where very thorough lead testing data allowed them to control for many confounding factors. The result:
This paper has not yet been peer-reviewed, so such an effect is not an ironclad certainty. However, prior knowledge and common sense militate powerfully towards accepting its thesis. We know for a fact that lead causes brain damage and sundry social malfunctions — indeed, there is a strong argument it caused the mid-century crime wave. If there's even a moderate chance of protecting children's brains with aggressive abatement, we should seize it.
And on the other hand, it's not like there's a risk of children getting too little lead.
Ideally the federal government should be the one to handle this problem. It has the deepest pockets, and the greatest reach throughout the country. Indeed, Hillary Clinton has proposed a pretty good lead abatement plan, attacking pipes, paint, and contaminated soil. But given probable Republican control of Congress, there's little chance this will pass in the near term.
However, the pockets of the school reform crowd are still quite deep. If the Gates Foundation decided to dedicate a significant portion of its $39.6 billion to systematic lead abatement, it could make a significant difference. It's a way to prevent child brain damage, improve school achievement — and all without needing to get in a brutal political fight with teachers. For a sensitive-minded billionaire, what's not to like?
