New York's high municipal spending relies on taxing a robust financial sector. As finance jobs decline and are replaced by lower-paid roles in sectors like healthcare, the city's tax base is eroding. This is compounded by a nearly 10% drop in real wages since the pandemic, threatening the city's governing model.

During tech gold rushes like AI, the most skilled engineers ("level 100 players") are drawn to lucrative but less impactful ventures. This creates a significant opportunity cost, as their talents are diverted from society's most pressing challenges, like semiconductor fabrication.

The US economy's perceived strength is fragile because it rests on a dangerously narrow foundation. Job growth is concentrated in healthcare, stock market gains are driven by a handful of AI giants, and business investment is similarly focused. This lack of diversification makes the economy vulnerable and fuels public anxiety.

The US economy is not broadly strong; its perceived strength is almost entirely driven by a massive, concentrated bet on AI. This singular focus props up markets and growth metrics, but it conceals widespread weakness in other sectors, creating a high-stakes, fragile economic situation.

For the first time in years, leading-edge tech is incredibly expensive. This requires structured finance and massive capital, bringing Wall Street back to the table after being sidelined by cash-rich tech giants. The chaos and expense of AI create a new, lucrative playground for financiers.

Fintech giant Ramp attributes its early hiring success to building in New York City. Unlike the hyper-competitive, short-tenure culture of Silicon Valley at the time, NYC offered a pool of talented engineers seeking long-term roles. This talent arbitrage allowed Ramp to build a stable, high-quality team and "punch way above its weight."

The immense salaries in software and finance may create a 'talent Dutch disease,' pulling the brightest minds from crucial fields like structural engineering. This reallocation of human capital could explain why productivity has stagnated or declined in industries that build the physical world.

According to Y Combinator partners, the network effects and density of talent, capital, and customers in San Francisco are so powerful that being physically based there can double a startup's chances of reaching a billion-dollar valuation compared to other major tech hubs like New York.

Instead of creating a tech sector from scratch, the most effective path is to identify and invest in tech niches adjacent to a city's existing industries (e.g., Energy Tech for an oil town). This leverages existing talent, infrastructure, and supply chains, making the transition more natural and sustainable.
