with run-down shacks approaching $1,000,000 in certain areas, I would be fine arguing that "middle class" is a misnomer. "working class slaves" is more apt, because we can dispense with the whole "working class" part, and shorten it to "wage slave."
Some people take offense at the "slave" terminology, but i suggest that if homelessness, death, illness, etc await you if you leave a working class job, you don't have a choice. HN has a bubble of thought that i bump against quite often, this is one of those ideas that i disagree with the zeitgeist on.
