Ridley: We Owe Our Prosperity to 2 Men From Glasgow

Key Takeaways

• 1776 saw Smith's "Wealth of Nations" and Watt's steam engine.
• Free exchange and cheap energy drove Britain’s industrial dominance.
• Linking heat to work amplified productivity, sparking modern growth.
• Modern policies raising energy costs risk stagnation.
• Lessons apply to US energy strategy and global competitiveness.

Pulse Analysis

Glasgow’s 1776 twin breakthroughs—Adam Smith’s articulation of spontaneous order and James Watt’s efficient steam engine—created a feedback loop that reshaped global economics. Smith’s insight that voluntary exchange and specialization generate wealth laid the theoretical foundation, while Watt’s innovation turned heat into mechanical work, dramatically increasing the energy return on investment. Together they ignited the Industrial Revolution, turning Britain into the world’s first high‑productivity economy and setting a template for modern growth that still underpins today’s digital and manufacturing sectors.

Energy economics remains a thermodynamic reality: prosperity hinges on converting abundant, low‑cost heat into useful work. Watt’s engine demonstrated that when heat fuels machinery, productivity multiplies, reducing the labor needed to meet basic needs. Contemporary analyses echo this, showing that economies with high energy return on investment enjoy faster GDP growth, lower unemployment, and higher standards of living. The shift from agrarian labor to steam‑powered factories illustrates how cheap energy amplifies the benefits of free markets, turning marginal gains into exponential progress.

Today, policymakers in the United States and Europe face a crossroads reminiscent of the 18th‑century debate. Restricting domestic fossil fuel development while subsidizing intermittent renewables can raise the effective cost of energy, eroding the competitive edge that cheap power provides. Nations that maintain affordable, reliable energy—whether through advanced nuclear, responsibly managed natural gas, or high‑efficiency renewables—are better positioned to sustain innovation, attract investment, and avoid the stagnation observed in economies that over‑control energy markets. Ridley’s historical lens underscores that the lesson of 1776 is timeless: cheap energy plus free exchange fuel lasting prosperity.
