HARRY MONROE: Mass production also came to the clothing industry. People began wearing clothes made in factories, instead of by a family member or local tailor. Before long, the same kinds of clothes could be found everywhere.
Mass production removed some differences that had marked Americans in the past. Prices dropped, so people with little money could still buy nice clothes. It became more difficult to look at Americans and know by their clothes if they were rich or poor.
KAY GALLANT: Social changes also resulted from great progress in medical research.
Doctors and scientists reported new developments in the fight against disease. This progress gave most Americans a longer life. In nineteen hundred, for example, the average person in the United States could expect to live forty-nine years. By nineteen twenty-seven, the average person could expect to live fifty-nine years.
HARRY MONROE: Life expectancy rates climbed, because doctors and scientists developed effective ways to prevent or treat diseases such as tuberculosis, typhoid, diphtheria, and influenza. Yellow fever and smallpox were no longer a threat.
One new medicine was insulin. It was used to treat diabetes. A man-made version gave diabetics the insulin their bodies did not have. It cut the death rate from the disease from seventy percent to about one percent.
Doctors and scientists also learned the importance of vitamins to good health. Now they could cure several diseases caused by a lack of vitamins.
