The article may be referring to page 14, actually.
The question on page 14 is "Do you think the American Dream--that if you work hard you'll get ahead--still holds
true, never held true, or once held true but does not anymore?
And the results are (from 2023 to 2025):
Still holds true: 36, 34, 31 (downward trend)
Never held true: 18, 17, 23 (upward trend)
Once held true but not anymore: 45, 49, 46 (mixed trend)
Its a report on how people feel. It measures how people say they feel. It's limited in usefulness but not worthless. Id just hazard against reading too much into it.

Including previous values:
25% July 2025
29% July 2024
28% March 2023
27% May 2022
Interesting other measurement:
Neither agree nor disagree: 32% 24% 28% 27%
So... not really much change over the past 3 years.
