> Why do we not have the same goals for automotive mechanics?
A lot of industries that have issues attracting certain kinds of people don't have explicitly diversity goals as a part of their makeup. But that doesn't mean that people aren't trying to break into those industries and have a career there.
Keep in mind that the kind of work you do isn't just influenced by your hobbies and likes, but also by what is considered acceptable for a certain person based on gender/race/etc., stereotypes about kinds of work, and classism (among other things).
