Ever wondered how America became so wealthy so quickly? The 1920s economic boom transformed how Americans lived and worked. Mass production, pioneered by Henry Ford's assembly line, made cars and other goods affordable for ordinary families.
Ford's Model T dropped from expensive luxury to just $290 by 1925, thanks to efficient production methods. Workers learned specific skills to assemble parts quickly, boosting output whilst keeping costs low. This created a cycle where higher production led to lower prices and greater demand.
The automobile industry became the backbone of American prosperity. Car registrations jumped from 8 million in 1920 to 23 million by 1929. This growth created jobs for 3.75 million people and stimulated demand for steel, rubber, and glass industries.
Consumer culture exploded as people began buying goods through hire purchase (paying in instalments). Americans spent 8 billion by 1929. Low unemployment and rising wages meant families could afford radios, electrical appliances, and cinema tickets.
Key Point The assembly line didn't just make cars cheaper - it revolutionised how everything was made, creating the modern consumer economy we know today.
