Because we are an anxious, internally focused movement, we see the "class" issue as this: are our congregations friendly and welcoming to people who are poor or working class? We fret about things like "is a requirement for a financial contribution for membership unwelcoming?" Or "Do we assume too high an educational level to understand our sermons?" One congregation I was in argued about whether they should use wooden salad bowls or donated shiny metal collection plates to take the collection.
The question is: "are UU congregations friendly and welcoming to poor and working class people?"
Another, more important, question is: "Are UU congregations on the side of poor and working class people in the conflicts and controversies of our day?"
Do we support the efforts of community unionizing, like the Walmart workers or the fast food workers of New York? Are we on the side of public sector unions when their rights to organize as being restricted in Wisconsin? Do we oppose the Michigan turn to right-to-work status? Are we in favor of uninsured workers getting health insurance from someone? Do we think minimum wage workers should get a raise?
UU's are generally silent on issues of class for many reasons, but mostly because we have never thought them through.
Unitarians and Universalists were involved with 19th century utopian communities (Hopedale, Brook Farm etc.) because they had a revulsion to the rise of industrial capitalism.
What are the traditions and concepts and enduring values that could guide us in these issues?
