Is the financial sector a net drain on society or a driver of growth?

Does Finance Benefit Society? · 53:14 · Video: Gresham College · Watch at the source

In short: Since the 2007–10 financial crisis, many view finance as a parasitic, rent-seeking industry. While academics argue that finance fosters entrepreneurship and alleviates poverty, public trust has plummeted. Is the stock market merely a series of speculative side-bets, or does it provide essential value even without raising new capital?

The debate over finance's utility often pits academic theory against public perception. For many, the financial sector is seen as a source of rent-seeking activity rather than value creation. This skepticism was fueled by the 2007–10 financial crisis and subsequent scandals involving Libor-fixing, gold-price-rigging, and subprime mortgage fraud. In the United States, a 2014 Chicago Booth/Kellogg survey found that 48 percent of adults believe the financial system hurts the economy, while only 34 percent believe it benefits it.

Academics like Luigi Zingales argue that finance provides critical opportunities by allowing talented individuals to start firms without needing inherited wealth or long-term savings. This mechanism is intended to promote growth, innovation, and a better allocation of resources. Furthermore, finance can help manage risk, provide price signals, and reduce inequality. Nevertheless, detractors argue that equity markets fail to provide a net capital surplus; for example, funds used for repurchasing shares often equal those gathered via new offerings, while much activity involves speculative wagering among traders.

The disconnect between these views is significant. In 2010, 57 percent of Economist readers disagreed that financial innovation boosts economic growth. This gap suggests that even if finance performs essential functions, the industry must address public mistrust. Academics face the challenge of bridging this divide, ensuring that their specialized knowledge does not lead to a dismissive 'groupthink' that ignores valid societal criticisms regarding the industry's impact.
