Final answer:
The majority of the 50.6 million projected job openings in the U.S. by 2022 are due to retirements and the need for replacement workers, with higher growth in jobs that require more education and training.
Step-by-step explanation:
The 50.6 million job openings projected to occur in the United States by 2022 are largely due to retirements and the need for replacement workers. This trend indicates that as the workforce ages, there will be a significant number of openings simply because current employees will be leaving their positions. Moreover, employment trends suggest higher growth rates for jobs that require more education and training.
For instance, jobs requiring a professional or master’s degree are expected to see a 20 to 22 percent growth. In contrast, positions that only require a high school diploma are predicted to grow at a slower rate of 12 percent. As immigration plays a role in the U.S. workforce, the economy tends to absorb new workers without causing long-term shifts in unemployment rates.
