Thanks to Jared Kushner's official position in his father-in-law's administration, the subject of nepotism has been in the news. One legendary adherent of this practice was original Hollywood mogul Carl Laemmle. He placed countless relatives on the payroll at Universal Studios.
One cannot condemn nepotism based upon the example of Carl Laemmle. The results were sometimes good. One cousin whom Laemmle imported from Europe was failed haberdasher William Wyler. He became one of Hollywood's great directors, and was Bette Davis's favorite. Fourteen actors, including Davis, won Academy Awards for their performances in his films. Moreover, had not Laemmle employed Wyler and the other Laemmele relations, they likely would have been trapped by the dark clouds then forming in Europe and perished in the Holocaust.
Note: William Wyler became a great success not at Universal Studios, but after he departed and began collaborating with Samuel Goldwyn.
