Answer:
The premise of Pollack and Olen's book states that the best personal finance advice can fit on a simple index card and it is available for everyone in the nearest library.
Explanation:
Harold Pollack is a social scientist. In 2013, he interviewed personal finance writer Helaine Olen about her book, Pound Foolish, and during the interview he shared his thoughts about this issue.
He said, the best personal finance advice can fit on a simple index card and it is available for everyone in the nearest library, this was just an idea and he did not elaborate on the specific financial advice. After the video was posted, he received a lot of emails asking about the index card but it didn't even exist, so he decided to write it down and post it online.
The photo went viral and later on, Pollack and Olen teamed to write a book, The Index Card: Why Personal Advice Doesn't Have To Be Complicated.
It became an instant success thanks to all the influence awakened by the previous post of the index card and people were expecting to know more about it, so the promotion for the book was partially done already
