Many UU's have these experiences in their Pasts: some as the persistent condition of their childhoods and some as temporary situations on their life's journey.
Some UU's are in these circumstances in the Present, or they have family members who are, and they live in communities in which low-wage workers are all around them everyday.
And for many UU's, these positions are their Future, as retirement savings turn out to be inadequate, as full employment gets redefined as 6%, as misguided austerity shreds the safety nets, as the rich get richer and the poor get poorer and the middling classes get forgotten. The younger see it more clearly than the old.
This is not Unitarian Universalism's self-image. We tell a self-story that denies our own reality. It is called "false consciousness" and a lot of it is going around.
