Automobiles have made a big difference. By the 1990s, they had went worldwide. One of the people who helped them go a long way was Henry Ford. He made a continuously moving assembly line to make the production of autos go faster; so, they could get around the world faster. Before Ford’s big difference, less than 1000 vehicles were sold a year; now, more than 80 million new ones are sold each year, according to Phil LeBeau of CNBC. The need for more cars caused a sudden change in the production of steel aluminum, petroleum, and rubber industries. So, cars are also helping with employment.
