Final answer:
True, in the U.S., the service sector does provide almost 80% of all jobs. This change reflects the country's transition to a postindustrial service economy, deeply impacting job quality and economic inequality.
Step-by-step explanation:
In the United States, the statement that the service sector provides almost 80% of all jobs is true. The economy has experienced a significant shift from the primary and secondary sectors to a postindustrial service economy. This shift is due to the rise of the information age, where more people are employed in services related to entertainment, tourism, media, healthcare, financial and legal industries, and education. The growth of service sector jobs has been a defining feature of the U.S. economy since 1970.
While some service sector jobs are well-paying, such as computer programming, others are not and may contribute to economic bifurcation and increasing inequality. The shift from manufacturing to service jobs has also led to a decrease in jobs that were previously accessible to individuals without a college degree but still offered reasonable wages. Consequently, there's a widening gap between the economically well-off and those struggling, often referred to as the 'haves' and 'have-nots.'
