In 2025, U.S. banks generated a staggering $434 billion in net interest income, or about $1,670 per adult, according to research from River. This figure underscores a significant issue in America’s financial system: the extraction of wealth from savers through the interest rate spread, a mechanism that quietly erodes purchasing power and benefits banks at the expense of consumers.
The Mechanism of Wealth Extraction
The process is straightforward: banks take customer deposits, lend or invest those funds at higher rates, and return only a fraction of the yield to depositors. With most savings accounts offering negligible interest, the disparity in rates creates a reliable profit engine for banks. Meanwhile, inflation has consistently outpaced the Federal Reserve’s 2% target, further diminishing the value of savings. When your bank pays 0.1% interest but inflation is several percentage points higher, the result is not just stagnation—it’s a loss of purchasing power.
The Fintech Paradox
The fintech sector, once heralded as a corrective force after the 2008 financial crisis, is now facing its own identity crisis. Platforms like Robinhood, Coinbase, and Cash App have democratized access to financial tools, but the mission has drifted. What began as a movement to empower users has, in many cases, turned into a strategy to monetize user behavior.
Alex Leishman, CEO of River, argues that the line between investing and entertainment is becoming blurred. Investment platforms now promote high-risk assets, such as memecoins and leveraged derivatives, and incorporate casino-like features. While these features may drive engagement and generate revenue, they often leave users worse off. Data shows that most retail participants lose money in high-frequency trading environments, and personal bankruptcy rates have risen in jurisdictions where sports betting has expanded.
The Case for Bitcoin
Bitcoin offers a stark contrast to the existing financial system. Unlike traditional banking, Bitcoin does not promise yield or rely on user engagement to sustain itself. Its value proposition is simple: a fixed supply, a decentralized network, and the ability to self-custody without intermediaries. Despite its growth, Bitcoin ownership remains relatively low, with less than one-fifth of American adults holding it. This suggests that while adoption is still in its early stages, the gap between the current financial system and viable alternatives is significant.
Realigning Incentives
The original promise of fintech was to expand access and improve outcomes. While it succeeded in the former, the latter remains a challenge. Banks continue to extract value through interest rate spreads, and fintech platforms increasingly optimize for activity over outcomes. Users are left navigating a system that often rewards participation more than prudence.
The opportunity, as Leishman frames it, is to realign incentives: build tools that prioritize long-term wealth creation over short-term revenue and offer products that founders would trust their own families to use. Bitcoin, with its rigid and transparent framework, may be a key part of this realignment.
Looking Forward
The financial landscape is evolving, and the tension between traditional banking, fintech, and decentralized alternatives like Bitcoin is likely to intensify. As more people become aware of the structural issues within the current system, the demand for transparent, user-friendly, and equitable financial tools will only grow. Whether Bitcoin can fully meet this demand remains to be seen, but it is increasingly positioned as a viable alternative for those seeking a different path to financial security.
