What if the best financial advice isn’t new—but simply forgotten?

In this episode of Earn & Invest, Doc G sits down with historian Joseph S. Moore, author of How to Get Rich in American History: 300 Years of Financial Advice That Worked—and Didn’t. Moore spent a decade exploring centuries of advice aimed at everyday Americans, testing which strategies actually worked—and which didn’t. Remarkably, his research led him to build a seven-figure net worth using lessons from the past.

Moore’s journey began with a personal financial scare: after taking a risky “NINJA loan” to buy a townhouse in 2005, he realized his vulnerability as the Global Financial Crisis of 2008 approached. Selling his home just in time sparked a curiosity that would consume the next decade.

One of his most surprising findings? Optimism is a powerful predictor of financial success. Research from the Consumer Financial Protection Bureau shows that believing you can shape your financial future often outweighs inheritance or education. Moore argues that financial “gurus,” often dismissed for overhyping strategies, actually provide hope and practical frameworks that help people take action.

We also explore how many “modern” wealth tactics are centuries old. House hacking—renting out spare rooms to pay a mortgage—was once a standard working-class strategy, frequently managed by women whose contributions rarely appeared in official statistics. Mobility was another forgotten tactic; in the 1800s, roughly one in three Americans moved annually to chase opportunity.

Moore introduces the concepts of slow time and fast time: slow time is when we build skills, capital, and relationships; fast time is when booms, crashes, or major shifts create opportunities. Those prepared in slow time can seize advantage when fast time arrives.

We also discuss concentration vs. diversification, the myth of effortless compound returns, and why financial independence isn’t the finish line—it’s the point when life becomes flexible enough to pursue meaningful goals.

For anyone curious about wealth-building, historical financial strategies, or the patterns behind money and opportunity, this episode offers practical insights drawn from 300 years of experience.
