(apart from the obvious Marie Antoinette)

I'm not too clear on your reference here ...

You do mean that a similar thing was allegedly said by Marie Antoinette when told the people had no bread : "Let 'em eat cake." Don'cha?
No offense, just checking!
Some years ago I read an apologia which posited there was a "cake" available at the time that was made with much cheaper ingredients than those necessary for bread so therefore more readily available ... the point being Marie A was not as cold as the remark would indicate.
