Frau Heinz is a Mozambiquean doctor's daughter, not a real aristocrat or even a member of one America's founding families. She married her money and influence. Absent Sen. Heinz's upper class standing, there's no way Theresa would be listed in the Social Register or be able to afford her gigolo Gianni Kerry the lifestyle to which he has become so easily accustomed.
Frau Heinz and Mrs. Bush are of solidly upper-middle class origins.
This makes all the talk about Frau Heinz the billionairess so risible: she's a nouveaux riche behaving with as little class as the stereotype of the parvenu would lead one to expect. This behavior did not begin until after her original mealticket died and left her the keys to the kingdom.
Mrs. Bush married into an equally upper class family, but one not nearly as locally prominent when she married in. She has always comported herself with grace and humility and does not appear to be status driven in the way Frau Heinz is.
Unfortunately, I believe some Dems view Lady Laura's grace as "plastic" and Hagetha Heinz's rudeness as "refreshing."
Laura is an incredible role model.
