While large investment banks are essential for major transactions, mid-tier banks are often better partners for proactively sourcing carve-out opportunities. They typically have to hustle more for deals, resulting in deeper, more personal relationships within potential sellers, which can unlock the off-market conversations that larger banks might miss.

According to Andrew Ross Sorkin, while bad actors and speculation are always present, the single element that transforms a market downturn into a systemic financial crisis is excessive leverage. Without it, the system can absorb shocks; with it, a domino effect is inevitable, making guardrails against leverage paramount.

America's system of nearly 10,000 banks is not a market inefficiency but a direct result of the founding fathers' aversion to centralized, oligopolistic British banks. They deliberately architected a fractured system to prevent the concentration of financial power and to better serve local business people, a principle that still shapes the economy today.

Core components of today's financial landscape, including FDIC insurance, Social Security, and even the 30-year mortgage, were not products of gradual evolution. They were specific policies created rapidly out of the financial ashes of the Great Depression, demonstrating how systemic shocks can accelerate fundamental structural reforms.

Maja Vujinovic posits that Gary Gensler, despite his pro-crypto past, was strategically positioned by banks to slow innovation. This regulatory friction gave traditional financial institutions the necessary time to understand the technology and formulate their own digital asset strategies before competing.

The Great Depression paradoxically created more millionaires than other periods. Extreme hardship forces a subset of people into a "hunger mode" where their backs are against the wall. This desperation fuels incredible innovation and company creation, provided the government clears regulatory hurdles for rebuilding.

The concept of 'banking deserts' extends beyond underserved regions. When specialized banks like SVB disappear, entire industry verticals (like tech, agriculture, or wine) can become 'underbanked.' This creates a vacuum in specialized credit and financial services that larger, generalist banks may not fill, thus stifling innovation in specific economic sectors.

The US banking system is technologically behind countries in Eastern Europe, Asia, and Latin America. This inefficiency stems from a protected regulatory environment that fosters a status quo. In contrast, markets like the UK have implemented fintech-friendly charters, enabling innovators like Revolut to thrive.

Major technological shifts create new industries in unpredictable ways. The spreadsheet automated manual financial modeling, revealing massive inefficiencies in companies. This enabled private equity firms to acquire businesses, streamline operations using this new tool, and extract value, effectively birthing the modern PE industry.
