i was also wondering this.

maybe because they seem to be more well off (wealthier than she)

oh, i got the impression it was the other way round. like cus she thinks they're "common," (pg399) they have lower social status.

don't know. definitely a societal issue though.

part of me believes she is envious of the way they live, it seems much more free than the Aunt's life.

I read some background & in the time Daisy is set americans were visiting europe for the first time & there were two types of tourists

Expats with American manners like Daisy and Expats that went above and beyond European manners and standards hence the treatment of Daisy
