The gender wealth gap isn't a myth. Women in the US retire with roughly 30% less wealth than men, on average. The pay gap is real, but it's not the whole story. The bigger issue is the investing gap — women are far less likely to invest, invest later when they do, and hold more cash relative to equities. The compounding math over 30 years is brutal.

Katie Gatti Tassin, creator of the Money with Katie podcast, wrote Rich Girl Nation as a direct response. Not as a lament, but as a manual.

The system wasn't built for you — invest anyway

Gatti Tassin is clear-eyed about the structural disadvantages: the pay gap, career interruptions, longer life expectancy requiring more retirement savings, and a financial industry historically designed to market to men. Understanding these forces matters. But understanding them isn't a strategy.

The strategy is: invest early, invest aggressively, and don't wait for a partner, a windfall, or a perfect moment. Every year of delay in starting an investment account is a year of compounding lost forever. The math doesn't care about fairness — it just rewards whoever started first.

Tax-advantaged accounts are the most underused tool

One of the book's most practical sections is on maximizing tax-advantaged accounts — 401(k)s, IRAs, HSAs. These accounts don't just reduce your tax bill; they change the trajectory of your wealth. A woman who maxes her Roth IRA from age 25 to 65 will end up with meaningfully more than one who starts at 35, even if she contributes the same total amount.

Gatti Tassin's point isn't that this is fair. It's that knowing it changes what you do this year.

Negotiate. Always.

Research consistently shows women negotiate salary less often than men, and are penalized socially when they do. Gatti Tassin's response: negotiate anyway. The financial penalty for not negotiating — especially early in a career when raises compound into every future raise — is far larger than the social discomfort of asking. Your future self is watching every negotiation you decline to have.
