Well, both buster and I have explained the Flynn Effect to you, do you understand it now?
PS and statistics show the more education people have, the more money they make, in general.
" A person's education level is significantly related to their annual income, with higher levels of education generally leading to higher earnings. For example, in 2024, those with a bachelor's degree or higher had a median household income of $132,700, more than double the $58,410 median income for households headed by someone with only a high school diploma. This earnings advantage reflects the skills, knowledge, and credentials that increase employability and allow individuals to command higher salaries in the labor market. "
