Dave Ramsey, Jordan Peterson, and Rachel Hollis are, each in their own way, three of our modern gurus. They’re a diverse group that reflects particular personalities of modern culture. Peterson is the philosophical academic, Hollis the Instagram celebrity, and Ramsey the folksy, financial counseling version of Dr. Phil. Their books don’t just sell; they live atop the bestsellers lists for years at a time. Hollis’s last two books are both currently in Amazon’s top 5. Peterson’s book 12 Rules for Life has sold 10 million copies since late 2017. You have scroll a bit further to find Ramsey’s manifesto The Total Money Makeover (and its various spin-offs), but then again, Ramsey’s radio show has been reaching millions of listeners since the George W. Bush administration.
