• it doesn’t have to be coaches and buggies tho, they could use rickshaws (do NOT let me fall into a Memoirs of a Geisha au please)
  
• there are likely very affluent districts and less affluent ones as well, but i’d like to think there’s no abject poverty in Erebor. like, let’s not assume the dwarves have fucked up socioeconomics as badly as we have 
• miners, for instance, wouldn’t be part of a lower- or poor class, but instead would be held in places of honor and paid very well for the dangerous and important work they do - after all, they’re directly responsible for unearthing the mountain’s wealth. why should they be underpaid just because they’re physical laborers? no.
• gender roles are virtually nonexistent because it’s better that way and dwarves are awesome and i said so
• the streets are kept clean and orderly; every citizen has a sense of belonging as well as ownership in the mountain

Bilbo called it “the greatest kingdom in middle earth” and i’m not about to take that lightly

EREBOR EVERYDAY STUFF IS SO IMPORTANT TO ME???

• venTIL ATION? how do you ventilate such a huge fucking mountain, so that nobody suffocates from the heat down low? there’s a lot of natural updraft and stuff like that, but god the master level skill that would have to go into carving out a webbing of ventilation shafts that pretty much work on their own is kILLING ME
  
• same goes for plumbing, I mean we saw in dos that they are no strangers to using water powered mechanisms, so I’m just imagining the sweltering heat and quiet plip-plop and of pipes running through the entire mountain, meeting in like this massive brain-like rattling sputtering structure somewhere where dwarves readjust their massive cogs and shit maybe that’s too steampunk but I love it anyway
  
• as for the farmyard animals, erebor is a MASSIVE self-sustained kingdom, the expenses if they were to import everything would be EXORBITANT, so I bet rachel’s right, they’ve found a really clever way to grow pastures for their livestock, and also have really resilient animals who don’t mind grazing on the (newly rejuvenated) mountainsides I bet
  
• as for the society aspect, I wouldn’t go so far as to presume they totally eradicated poverty, but they do have a very strong system that I still believe has a lot in common with a caste system (though looser), where you’re probably born into a guild and might be expected to take up that job, but nobody except for your overly traditional parents/grandparents/wider family is going to raise an issue if you decide to do something else
  
• dwarven pubs
  
• dwarven brothels
  
• dwarven LIBRARIES 
  
• DWARVENM ARKETS with like this entire MASSIVE cave spanning AT LEAST five floors dedicated to it and more adventurous buyers can rope right down the bridges if they know where they want to get, they’re selling uncut lapis lazuli down there again brb [whooshes into the depths of the mountain swan-dive style] (okay I’m exaggerating but you get the point)
  
• basically a dwarven kingdom works like a machine of its own, every single person is a cog in it and everyone has to work efficiently for the machine to operate smoothly oKAY FIGHT ME ON THIS (or alternatively send me more headcanons bc this is fun)
