This rhetorical substitution of economic class for social class has a particular virtue for people in more privileged social classes: it allows them to discuss the lack of privileges of the lower classes in a way that holds them blameless of bigotry. So it is okay -- preferred, even -- to discuss the difficulty of the poor to become non-poor due to lack of resources: how terrible it is that the poor are thwarted in their efforts to improve their employment by not having the money for interview clothing, for transit to better jobs, for qualifying education or training. Real problems all -- but also handy substitutes for discussing the much, much more uncomfortable topics of discrimination against job applicants and promotion candidates for having an accent, a hair-do, a sense of style, an address on one's resume that is lower-class.
Siderea goes on to cover several angles of the subject of moving from one social class to another, and this makes me think of a whole other subject:
People really hate changing their culture, and lots of political issues come down to cultural standoffs, where two cultures are incompatible and neither side wants to change, like when immigrants don't want to assimilate, or when old people don't want to adopt the values of young people. It's not always clear who's right, and sometimes the disagreements are over silly things like how to pronounce words.
But it gets interesting when political and technological changes favor certain cultures. The internet helps cultures that value transparency, and undermines cultures that value secrecy. Birth control helps cultures that value sexual freedom, and undermines cultures that want to harness sex to family obligations. I can even put my support for an unconditional basic income in cultural terms: it would undermine a culture of striving for conventional success, and feed a culture of learning to navigate free time.
By guaranteeing basic survival, a government provides a service as necessary as, say, policing the streets or fighting off foreign enemies. At the same time, once this service is provided, the government can get out of trying to regulate the labor market: Its goal of keeping people fed and clothed is already achieved.
Something fun, Every Meal In Wuthering Heights Ranked In Order Of Sadness. In college I was obsessed with Wuthering Heights and took four different classes that covered it. People think it's about romantic love when really it's about how modern society is a prison for the soul -- and apparently also about crappy food.
