I'm a homebody, so I don't even know what luxury would do for me. I don't like to drive, or go out of the house. I'm mostly in my room in front of the computer. If I had more money, I'd probably get a better monitor, upgrade my PC and setup. I know that's not a lot, but I guess I don't really want a lot of things at this point.
I think you aren't alone as homebody these days. I also wonder if this is part of the consumer cycle, isolating people into a lifestyle where more is spent on the self?
