When examining the relationship between education and earnings, the statement that holds true is:
b) Workers with more education tend to earn more and this effect has become stronger over time.
Research has consistently shown that higher levels of education are correlated with higher earnings. People who achieve higher degrees often have access to better job opportunities, higher salaries, and increased job security compared to those with lower levels of education. Moreover, over the years, data has suggested that the wage gap between college graduates and those with only a high school diploma has widened. This trend reflects the increasing demand for skilled workers in the labor market, making education an even more critical factor for economic success.
