A society needs people who can read, write and rithmatic. Whatever schooling you do after that is your own business.
Hoser ...
But as you say, "whatever schooling you do after that is your own business" has changed over time.
My father graduated from 8th grade and it was considered (back in 1936 or something) like an educational achievement. Today, having a high school diploma is like having, in some businesses, as having a roll of toilet paper.
You will need some trade school work or a bachelor's degree in something relevant (forget liberal arts, a degree in English, History or Poop that may get you an assistant manager's job at McDonalds or Taco Bell).
