I think this clip sums it up pretty well. Albeit, they're talking about living in tiny houses. But it's the same general idea. Joey's commentary is on point, IMO.

Also happens to be hilarious, but I don't disagree with the point he's making.

TL;DR Most people don't live like that because more desirable choices are available, and they're prepared to spend more to achieve that.
