The invention of the nineteenth century was a time of innovation, improvement, and rapid growth. The inventions of the 1800s changed American life. It improved the middle and upper class but had a negative effect on the lower class. New transportation, new manufacturing, and new communications have transformed many lives. First, the explosion of new inventions caused a major shift in American history; this event was called the Industrial Revolution. He came to the United States after Britain had the revolution which caused a ripple effect that led to the revolution in the United States. For example; Samuel Slater came from Great Britain and introduced a successful new textile mill to America. There were also many changes that came, including an increase in income and population in the cities. Furthermore, the new revolution caused the division of society into classes. One of these classes of people was the middle class. The middle class was an overall intermediate and middle class that lay between the other two classes. The other classes were the upper class and the lower class. The upper class was the highest class among all the classes and was also the richest. Furthermore, the last class was the lower class or more commonly called the working class. The lower class was the poorest and hardest working of the three classes. Inventions were the key to most of the changes that occurred during the revolution, hence the industrial revolution. Textile factories had a great impact in the 19th century. Introduced by Samuel Slater, a skilled British mechanic who immigrated to the United States, the first textile mill opened in Pawtucket, Rhode Island. Soon several textile mills were being produced in North America. Textile factories were used to......the means of paper......there was less control over one's destiny, since machines, although created by human beings, seemed to become their masters” (Frazer.D, 2013). This shows how the lower classes felt when they had to face so many difficulties to keep up with the innovation happening around them and when they had no choice but to work in unfair conditions. At the same time, the upper class and the middle class needed the lower class to stay where they were, as if there were blocks stacked high and the lower level was the lower class, the middle one was the middle class, and the upper one was the upper class. superior . If the lower classes were removed one by one, the structure would be unstable causing the collapse of the middle and upper classes. Just like it happened in the 19th century, when the lower class did not benefit from the inventions of the 1800s and the middle and upper class benefited greatly from them..
