The best time to launch a company is at the bottom of a recession. Key inputs like talent and real estate are cheap, which enforces extreme financial discipline. If a business can survive this environment, it emerges as a lean, resilient "fighting machine" perfectly positioned to capture upside when the market recovers.

Economic downturns cause panic, leading people to sell valuable assets like stocks and real estate at a discount. Those with cash and financial knowledge can acquire these assets cheaply, creating significant wealth. It becomes a Black Friday for investors.

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.

The entrepreneurs behind the 1930s mini golf boom demonstrated extreme resourcefulness. Some strategically located their courses directly underneath large, illuminated billboards. This scrappy tactic allowed them to operate their businesses at night without incurring any costs for electricity, maximizing their slim profit margins.

Robert Solow believes his cohort of economists became legendary not because they were smarter, but because living through the Great Depression focused their talent on society's most urgent problem: a broken economic system. This suggests that generational talent is directed by an era's critical challenges.

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.

Founder Rose Blumpkin's bias for action meant responding to challenges with immediate, unconventional solutions. When shotguns weren't selling during the Depression, she rented them. When her store burned down, she held a massive "fire sale" the very next day amid the wreckage.

Callaway is selling Topgolf for $1B after paying $2.5B four years ago. This loss highlights that businesses booming due to unique pandemic conditions may not sustain that growth, creating significant risk for acquirers who buy at the peak.

The recent surge in activities like sports betting and crypto trading is not a sign of generational degeneracy but a symptom of economic pessimism. When young people feel traditional avenues for building wealth, like homeownership, are blocked, they become more risk-seeking and turn to high-variance alternatives.
