LOS ANGELES — Walt Disney’s grandniece Abigail Disney, a critic of income inequality in general and the Walt Disney Company’s pay practices in particular, castigated the conglomerate anew on Monday, saying she came away “livid” about wages after a visit to Disneyland.

On Wednesday, Disney punched back, calling Ms. Disney’s assertions “a gross and unfair exaggeration of the facts.”

Ms. Disney, the granddaughter of Roy O. Disney, who founded the entertainment company in 1923 with his brother Walt, appeared on the Yahoo News video series “Through Her Eyes” this week. The interview touched on a range of sensitive topics — her archly conservative parents were, at times, abusive alcoholics, she said — but her comments about wages for Disneyland workers in California were widely picked up online.

“I went to Anaheim, and I wanted to be sure I understood the situation and the context really, really well,” Ms. Disney said. “Every single one of these people I talked to were saying, ‘I don’t know how I can maintain this face of joy and warmth when I have to go home and forage for food in other people’s garbage.’”
