There’s a persistent myth floating around personal finance circles that earning more money doesn’t really matter if you live somewhere expensive. The logic sounds superficially reasonable: a $200,000 salary in San Francisco leaves you with less purchasing power than $80,000 in rural Tennessee, so why chase the bigger number? It’s a comforting idea, especially for those who’ve chosen lifestyle over income. But it doesn’t hold up under scrutiny. Almost universally, earning more money is better — full stop.
Savings Rate Is What Actually Builds Wealth
The most important number in personal finance isn’t your salary. It’s the gap between what you earn and what you spend. A higher income, even in a high cost-of-living city, almost always produces a larger absolute surplus than a modest income in a cheap town. If you earn $180,000 in New York and spend $120,000, you’re saving $60,000 a year. If you earn $70,000 in Omaha and spend $50,000, you’re saving $20,000. Yes, your New York lifestyle costs more. But the delta — the raw dollars flowing into your future — is three times larger. Wealth is built in dollars, not percentages of local rent.
Expenses Have a Floor, Not a Ceiling
Here’s something the “cost of living cancels it out” crowd tends to overlook: expenses in a high-cost city are higher, but they’re not infinitely scalable. Your rent goes up, your groceries cost a bit more, maybe you pay more for a gym membership. But you still only need one apartment. You still only eat three meals a day. The marginal cost of living doesn’t rise in lockstep with income — it rises much more slowly. A person earning $300,000 in Boston doesn’t spend $300,000 just because the city is expensive. The surplus at high income levels is enormous even after accounting for a pricier environment.
Optionality Is a Form of Wealth
Money buys something that’s hard to quantify but impossible to overstate: the freedom to make choices. Higher income doesn’t just mean more consumption today. It means you can leave a bad job without panic. It means you can weather an unexpected medical bill, a divorce, a job loss, or a recession without financial catastrophe. It means you can support aging parents, fund your children’s education, or retire early if you choose. A person earning more in an expensive city isn’t just buying avocado toast — they’re buying resilience. The person who earns less in a cheap town might have lower monthly stress, but they have far less margin for error.
You Can Always Move. Your Income Doesn’t Follow You Automatically.
One of the more powerful arguments for chasing income is geographic arbitrage — and it cuts the opposite way from what people assume. If you build a high income in an expensive city, you can eventually take that income (especially in the remote-work era) and relocate somewhere cheaper. Suddenly, that San Francisco salary funding a life in Chattanooga makes you extraordinarily wealthy by local standards. The reverse is much harder. A moderate income earned in a low-cost area rarely follows you upward. You can move to New York on a Tennessee salary, but you’ll struggle. Income potential is often tied to industries, networks, and markets concentrated in expensive places. Earn the most you can first, then decide where to live.
Inflation Favors the Higher Earner
Over time, inflation erodes purchasing power. The person with a higher absolute income has more capacity to absorb price increases, invest in inflation-resistant assets, and adjust their financial strategy. When the cost of groceries, energy, or housing spikes — as it has dramatically in recent years — the higher earner bends, while the lower earner breaks. There is a genuine and meaningful difference between finding a price increase inconvenient and finding it catastrophic. Higher income is a permanent structural buffer against economic shocks that affect everyone, rich and poor, in every city and every town.
The Psychological Case Is Overstated
Proponents of the “earn less, live better” philosophy often lean heavily on studies showing that happiness plateaus around a certain income level. This research has been widely cited, widely misunderstood, and significantly revised over time. More recent work suggests that for most people, wellbeing continues to rise with income well past the figures often quoted. More importantly, even if happiness does plateau at some level, that’s an argument for not obsessing over income beyond a comfortable threshold — not an argument for actively choosing a lower income. The ceiling on income-driven happiness is not a reason to stay close to the floor.
Giving, Investing, and Legacy
There’s a dimension of higher income that purely self-interested analysis misses: the capacity to do good. Higher earners can give more to causes they believe in, support their communities, fund scholarships, back small businesses, and leave meaningful legacies. The ability to be financially generous is not trivial. It matters to most people’s sense of purpose and identity. Living frugally on a modest income in a low-cost city is a perfectly respectable life — but it forecloses a category of meaningful action that more money makes possible.
None of this means you should sacrifice everything for a paycheck. Health, relationships, autonomy, and purpose all matter enormously — and no salary compensates for their absence. The argument isn’t that money is all that matters. It’s simpler than that: given a genuine choice between more income and less income, more is almost always better. The cost of living is a variable you can manage, move around, or arbitrage. The income you didn’t earn is simply gone.Choose the bigger number. You can always decide later what to do with it.
