January 17, 2026, 1:32 PM EST. On The Ramsey Show, Dave Ramsey argues that the so-called secrets of the rich are not secret. Wealth, he says, rests on simple, familiar bets and focusing on what you understand. He cites a $200 million rancher who concentrates on farmland to show wealth can come from expertise, not gimmicks. Ramsey warns against chasing trendy investments or following friends who lack transparency, citing Bernie Madoff as a cautionary example. He endorses the KISS principle and sticks to three core investments: his business, paid-for real estate, and mutual funds. He rejects single stocks, gold, and crypto as speculative. The approach echoes Peter Lynch's adage to buy what you know; Lynch's Magellan fund grew from $20 million to $14 billion AUM.
