When I was in high school, back in the dark ages, our counselors were just teachers who had a free period. Not a one of them, as far as I can remember, had a bit of training or talent for counseling callow youth.
If you were a "college material" girl, you were advised to go into teaching or nursing because "you could always go back to work after your children were old enough for school", never addressing the prospect that a woman just might have to work practically non-stop for the rest of her employable days. And if you were counseled to become a teacher, it was always English or Literature or Elementary Education. Girls were not encouraged to become math or science teachers.
Not going to college. Well, make sure you take shorthand and typing because "you can always go back to work after your children....."
"College material" boys were pointed to medical school, engineering, law, accounting. "Jocks", of course, were encouraged to become coaches, while teaching math or science.
The "hoods" were shuffled off to industrial arts or prodded toward the military (to "straighten" you out).
Also there was very little counseling aimed to making sure your high school days prepared you for college. Going to college? Take three years of Latin! You know what my three years of high school Latin did for me in college? Nothing. I found out my senior year in high school that I would have to "test out" of a year of foreign language before I could get any graduation credit for a course I took in college. And Latin only counted if I was taking Latin in college, which of course I wasn't. AND, even though I was majoring in journalism, I still had to take two years of "science" in college, all courses of which were geared to you having taken the earlier courses in high school. I took biology and botany in high school, both of which were "baby watered-down" classes. Neither of them helped me pass college science classes (of which I failed three).
When my daughter was in high school, she had a counseling session and asked "What can I make the most money doing that I'm interested in?" She was tested and advised to pursue law or accounting. She ended up in accounting, which lead her to making a lot of money. By then, the counselors were actually trained to work with the kids.
The kids today are being steered in the right directions. At my school, we were steered in directions based on our socio-economic backgrounds and gender.
Some of us made the right choices; some of us didn't.
