I see quite a bit more stuff among the regular middle classes that looks like pure signaling waste
Could you please list some examples? I've been trying to think of some myself, and I came up with things like gift-based holidays (Christmas, Father's day, birthdays, etc...), brand-name color-and-style-matching clothes, and the search for high status jobs (there is a reason "flipping burgers" is an insult). But it feels like there is so much difference between a homeless man living in a shelter with cheap food/clothing/electronics and a typical middle class man that I fear I might be missing something big, even after reading all the things you and lessdazed already mentioned. Which would bother me, because if it means I am unable to see the middle class as a special case of how to live a life.
I was browsing my RSS feed, as one does, and came across a New York Times article, "A Village With the Numbers, Not the Image, of the Poorest Place", about the Satmar Hasidic Jews of Kiryas Joel (NY).
Their interest lies in their extraordinarily high birthrate & population growth, and their poverty - which are connected. From the article:
From Wikipedia:
Robin Hanson has argued that uploaded/emulated minds will establish a new Malthusian/Darwinian equilibrium in "IF UPLOADS COME FIRST: The crack of a future dawn" - an equilibrium in comparison to which our own economy will look like a delusive dreamtime of impossibly unfit and libertine behavior. The demographic transition will not last forever. But despite our own distaste for countless lives living at near-subsistence rather than our own extreme per-capita wealth (see the Repugnant Conclusion), those many lives will be happy ones (even amidst disaster).
So. Are the inhabitants of Kiryas Joel unhappy?
