2026/09/14

Today we’re going to discuss what it means for a place to be “developed”. Development is often associated with economic success — that is countries with higher standards of living and material wealth like those found in Europe and North America. But as we’ll see, this perspective is only one way to compare countries on the global stage, has strong ties to colonialist histories, and doesn’t necessarily capture a place’s environmental and socioeconomic sustainability or even the population’s general

In 1955, the Supreme Court ruled unanimously that public schools should be racially integrated, and overturned the separate but equal doctrine established in Plessy v Ferguson decades before.
