Abigail Disney, heiress to the mass media and entertainment firm, voiced her support for a younger generation that she said is struggling with debt and afraid to take the same risk as their parents did.

"If (millennials) are angry I don't blame them," Disney, 59, told CNBC on Thursday. She argued that it was her generation of baby boomers who had made decisions around tax structures, public spending and the university system, that created the circumstances under which young people were now "laboring intensely and having a very hard time."

Disney's comments come a week after she took to Twitter to rail against her fellow boomers — the generation born between 1946 and 1964 — who took offence to the phrase "OK, Boomer."

While Disney said she was "a little angry at myself for jumping into the whole discussion because you can't make generalizations about generations," she understood millennials' frustrations.

Having raised millennials herself, Disney said she saw young people who wanted to make changes to the societal structure which was no longer the same as when her generation was young.
