What Industrialization Left Behind

Cheap steel is the hinge. The Bessemer process made steel affordable to produce at huge volume, so railroad companies could lay tens of thousands of miles of track across the country. Railroads connected local markets into one national market, so a factory in Pittsburgh could sell to customers in Kansas. Selling at that scale rewarded size: companies that could produce the most, cheapest, won, and they merged, bought out rivals, and formed trusts to control whole industries. That chain, steel to rail to national market to national corporation, is why names like Carnegie and Rockefeller define the era.

National wealth grew enormously, but it piled up at the top. Industrialists and financiers captured a huge share of the new income while wages for factory and tenement workers stayed low and hours stayed long. A country three times richer in 1900 still had more visible poverty than in 1865 because the growth was uneven, not because growth stopped. Meanwhile the federal government was never simply absent. It handed railroads millions of acres in land grants, passed protective tariffs that shielded domestic manufacturers from foreign competition, and only later, with the Interstate Commerce Commission in 1887, began regulating the companies it had helped build. Government was active throughout, just mostly on the side of business.

This concentration of wealth and this pattern of pro-business government are exactly what the next period reacts against. Progressives in the early 1900s built their whole agenda around correcting what the Gilded Age left unregulated: trusts, unsafe workplaces, child labor, and a government that had subsidized industry without protecting the people working inside it.
