It's not over-analysis - you have a sharp eye! That line is definitely a funny jab on Ashkenazim.
In Israel, many fans and TV critics have debated how social commentary plays in to the show. The diversity of the cast and some of the storylines definitely lend themselves to lots of self-humor.
Several TV critics did a deep dive on the portrayal of Ashkenazim in the show. They pointed out that the Ashkenazi characters have a lot in common, but also their differences:
* Shira is seen as the typical "liberal", middle class Ashkenazi who tries hard to seem OK with everything and everyone, puts work above all else, and tries to get everybody to get along.
* Mrs. Stretiner, on the other hand, is the super high-class Ashkenazi who is obnoxious to everyone because she is so rich and well connected she doesn't care what anyone thinks of her.
* While Titinsky is somewhat of a loser, but he is proud of being cheap and living with his mother. So maybe he's a winner in his own mind after all?
But that's what critics think - take of it what you will :)
My personal opinion is that with such a mix of people - Russians, Ethiopians, Ashkenazim, Mizrachim, etc. - everybody ends up getting mocked at some point. So full of chutzpah - and so Israeli!
Hope you like the show. We're going to be announcing the release date of season 2 very soon - and have a few more special announcements we think you're going to love!
Toda - thank you,
