This is a serious issue, and thanks for sharing the article. The president of the Mathematical Association of America, David Bressoud, was at the hearing mentioned in the submitted article calling for more programs to encourage women and ethnic minorities to participate in higher education in math. This is an ongoing concern of professional organizations of mathematicians in the United States.

But just as a possibly illuminating contrary view, the controversial article by Philip Greenspun

may be on point here. Maybe there are better opportunities for young people who are being recruited into math and science than the opportunities provided by math and science careers.

(Note on personal background: my oldest son, who is in the process of applying to colleges when he doesn't plan his start-up, intends to major in math and computer science, and has taken upper-division courses in each subject already. But he is not part of the population groups mentioned in the submitted article.)
