I had the same thought. My friends and family are all mostly in the same income bracket, and "don't have the money" would be an obvious lie for all but the most expensive event (recent example was a luxury safari in Africa at >$10k/head).
There's a difference between "don't want to" and "can't do".
But, we have a pretty tight-knit group of friends, most of whom live within walking distance, and due to kids, we usually just have dinner at somebody's house. We're boring white collar suburbanites, I guess.
