Final answer:
Government investment in human capital can shift based on factors such as economic development and aging population.
Step-by-step explanation:
Government investment in human capital is likely to shift depending on a variety of factors. In low-income nations, additional investment in human capital through government spending on education is likely to increase productivity and growth. However, in countries like the United States, critics question how much government spending on education actually improves the level of education. As the population ages, there may be a higher demand for government services, leading to increased government deficits, which could impact investment in human and physical capital that is essential for economic growth.
