There is a similiar piece in Salon by Amanda Marcotte that also discusses the overarching family dynamic.

The whole performance relies heavily on gender stereotypes. It's the common trope of the loud-mouthed man kept in check by a stable and honest woman. Typically, the combo is a literal married couple, especially in the world of sitcoms: Archie and Edith, Fred and Wilma, Homer and Marge, etc.

In reality, Ivanka was in on the con, as the Forbes journalists figured out by checking her claims next to the real world numbers. The sitcom couple routine seems to have worked, however, on investors who were snookered by the Trumps. It also works to dupe Trump supporters, who frequently point to Ivanka's alleged level-headed sincerity as proof that her father ain't so bad. It doesn't matter that she's a bad actress. These stereotypes are so ingrained in people that they don't need good fakery to believe.

The piece continues by identifying continuity between Trump's sudden fixation upon the judge's clerk and Elise Stefanik's willingness to perpetuate what Trump and his lawyers were formally forbidden by a gag order from continuing, by instead harrasing the judge himeself in the form of bogus ethics complaints.

If you step back and observe all of what is going on in the world from the perspective of a combined zoologist and psychiatrist, it is very easy to see how easily "humanity" in humans can be warped by a sick environment and literally breed generation after generation of psychopathy and misery. For bored billionaries and kids raised in a perpetual war zone, alike.
