If a country does not invest in its human capitol how can it affect the country's GDP?

If a country fails to invest in its human capital, it can lead to a less skilled and efficient workforce, ultimately hampering productivity and innovation. This lack of investment can result in lower economic growth and diminished competitiveness in the global market. Consequently, the country's GDP may stagnate or decline, as a poorly educated and trained population is less capable of contributing effectively to economic development. In the long run, this can perpetuate cycles of poverty and inequality, further undermining economic performance.
