Carnegie built his empire through vertical integration of steel production, cost discipline, and timing the expansion of railroads and infrastructure. By the 1890s, his companies dominated rails, bridges, and ships, allowing unprecedented scale.
His 1901 sale to J.P. Morgan created U.S. Steel and crystallized his personal peak fortune, which newspapers of the era struggled to describe in modern terms. Understanding that environment is essential for interpreting today's comparisons.
