In the 1870s, America was booming with new factories, railroads, and inventions and iron molders were right at the center of it. These workers earned about $2.63 a day, usually working six days a week for 10 to 12 hours a shift. Over a year, they made around $820, just enough to cover basic needs like 2-cent cornmeal, 33-cent coal, and $4 boots. The work was grueling: molders poured molten iron into molds to create machinery and building parts, often facing intense heat, choking smoke, and the constant risk of burns or accidents, with little to no safety rules to protect them. At the time, gold was worth about $20.67 an ounce, meaning a full year’s wages could buy roughly 40 ounces. Today, with gold prices over $2,300 an ounce, that same year’s work would be worth more than $90,000. Taxes were lighter too. After the Civil War, most income taxes had been repealed, so workers mainly paid hidden costs through tariffs rather than losing money directly from their paychecks. By today’s standards, life for iron molders was harsh. Modern ironworkers now make between $45,000 and $70,000 a year, work 40 hour weeks, and have strong unions, safety protections, and benefits. Back then, the men who took on this dangerous work helped lay the foundations of America’s industrial strength with nothing but grit, sacrifice, and sheer determination, a legacy that still supports the nation today.
