Trina Paul at Investopedia posed the question people argue about at dinner: would you rather earn $150,000 in New York City or $80,000 in a low-cost city? Most people treat it as a lifestyle preference. I told her the salary-to-cost comparison misses the real planning question entirely.
The real question is career stage. NYC's network density can carry a decade of career acceleration that cheaper rent never will. At 32, the people you meet, the roles you get pulled into and the raises that follow compound in a way that no cost-of-living calculator captures. That premium has a shelf life, though. At 35 the density compounds your earning trajectory. At 58 it probably does not, at least not the way it used to.
That is why the decision about where to live is not just a lifestyle choice. It is a retirement income decision dressed up in zip code language. The years between 52 and 62 are often the highest earning and highest accumulation window a person will ever have, and where you live during that window materially shapes what retirement looks like.
If you are in your 50s and still anchoring your income plan to a high-cost city for the opportunities, it is worth modeling what staying actually costs in retirement savings capacity. For someone at 32, the answer is usually to stay and compound. For someone at 55, it is often the reverse.
