I can't believe I've never encountered Michael O. Church.

Via @BillySmith, I read his remarkable 2012 taxonomy of three distinct "ladders" of social class, within which sit 13 social classes. It's perceptive and useful and filled with trenchant social commentary. And accessible only via the Wayback Machine https://web.archive.org/web/20180528153508/http://sasamat.xen.prgmr.com/michaelochurch/wp/2012/09/10/the-3-ladder-system-of-social-class-in-the-u-s/ 1/

In 2021, he revisited the issue: "Marx was right. If there are stable social classes, there are exactly two of them." His 2021 worldview is darker, sadder, and rings too true. https://michaelochurch.wordpress.com/2021/01/28/a-reply-to-alex-danco-revisiting-macleod-and-the-three-ladders-in-the-wake-of-trump/

They're long! I recommend reading them both. /fin
