Final answer:
Modern farmers and industrial workers have significantly increased their productivity, with farmers working 10 or more hours daily and one farmer producing enough food for 50 people. The average industrial worker currently works around 42-54 hours per week.
Step-by-step explanation:
Industrialists and farmers have shown dramatic increases in productivity over time due to advancements in technology and production methods. From the information provided, it seems that many farmers today work for 10 or more hours each day. In the past, this intense labor produced enough food for a farmer's own family and sometimes a small surplus. However, by the 1970s in the United States, the situation had evolved so that one farm worker could produce sufficient food for 50 people. Additionally, the average U.S. worker has more than doubled their productivity since the 1970s, according to the Bureau of Labor Statistics. In figures related to worker productivity, the U.S. economy shows that in industrial fields, workers on average spend about 42-54 hours per week working.
