Fascinating perspective! I don't think anything in my house cost over $500, including beds, couch, TV and appliances. What item can you get for $14k?
I think a Stickley dining set or side hutch is probably ~$12k not on sale, and a sofa could probably go anywhere from $6k to $20k, but YMMV. (I don't personally own anything like that.)
But even brands like Herman Miller or Ekornes can really add up. (And I don't think of them as being the highest-end of things. Even hiring a quality woodworker to make something for you can end up similarly priced depending on detailing, finish, wood species, etc.)
One Eames chair is about $6-7K. (Not that I own but, but I'd take a donation ;) )
Check out design within reach. Fancy furniture can be incredibly expensive.
Here's a couch from a retail store you've probably heard of that you can configure online for $12k.

Personally I'd rather buy one from IKEA and use the change left over from $12k to buy.. a used truck to drive the sofa home in.. but apparently there's a market.
You can certainly go much higher for smaller companies producing actual custom stuff, using exotic materials, for a giant sectional instead of a single sofa, etc.
