Sorry for this question. I am still learning.
Something that has always bothered me is how much u.s. politicians obsess over helping the middle class. Seems like the two major parties talk about it a lot. Why do they endlessly talk about helping the middle class, but never seem to acknowledge or focus on helping the (lower?) or poverty or proletariat class?
To me it sounds like the middle class by definition should be not be as in need as other classes that don't have as much? What's the purpose of this?
Because the "middle class" is a fictitious category that everyone from people struggling to stay above the poverty line to literal millionaires think they belong to. It's what "respectable" people are, the small landholders and people who aspire to own land.
It was cynically created by encouraging suburban land ownership among certain privileged (white) working class demographics, and later reinforced by encouraging tying small amounts of stock ownership into pensions or workers' benefits. It's a way of making workers mistakenly see their own material interests as being aligned with the ruling class's, and insulating them against reforms that would benefit them directly at the cost of meaning less value for the meager property they've acquired.
