An article on "equity", which is tl:dr, but it's a hook for a memory--we're coming up on the 55th anniversary of the launch of Sputnik, which set off a panic. The wikipedia article is rather narrowing focused. My memory is that education was impacted as well--sputnik was seen as reflecting weaknesses in US schools, particularly in math and science. There was also a perceived lack of focus on talent; education schools were seen as under the influence of John Dewey and progressive education.
Part of the response to Sputnik was the 1958 National Defense Education Act, which included student aid and an emphasis of science.
We didn't talk about equity back then, but it seems the pendulum has swung the other way now.
