David. O. Sacks: Books

The Diversity Myth: Multiculturalism and Political Intolerance on Campus

This book was written in 1995 by Sacks coworker and his former PayPal boss, Peter Thiel. The book shines a light into the perspective that both men had on education and politics in general. It takes on what both men viewed as the “debilitating impact” of political correctness and multiculturalism on college campuses, arguing with force that both of these concepts were making a dramatic negative impact on education and higher education in the United States. It specifically discusses the experience that both men had while learning at campus.

As you might surmise from the book, it is written from a conservative perspective, and in that regard, it highlights the conservative political philosophy of both men. However, Sacks would not ultimately stick to his belief in everything he wrote: In 2016, he apologized for portions of the book. Sacks caused controversy when referring to date rape as “belated regret,” and he would come to disavow those remarks.
