This article explores the passage and failure of the 1973 Illinois Resource Equalizer formula which was designed to reduce disparities in school finance by breaking the connection between local wealth and school revenue. It argues that two sets of goals drove passage of the new law--equity and local property tax relief--and they came into conflict during implementation, with the latter winning out over the former. It argues that to understand both the passage and failure of the law requires looking deeply at the politics, policies, and practices of taxation, especially the methods of assessing property and levying taxes, where officials made decisions about how to apportion burden and benefits. The Illinois Resource Equalizer story highlights the political and policy choices that structure inequality through school finance at a moment when it was quietly defended and deepened.
