"It seems wholly unremarkable, to me, that people who work hard, try to anticipate the needs of their employers, keep the big picture in mind, and take initiative are more valuable employees."
Sometimes they are. Sometimes they aren't. Different roles are going to require different personality types. There are scenarios in which "complacent, trustworthy, consistent" are the 3 most important traits someone needs for a role. Those things may also combine with the other skills you're mentioning, but not always.
Some roles just don't have a career track for advancement, and there's plenty of times where advancing an employee is less beneficial to a company overall so it's best to hire for someone who's just going to settle into their role and be happy with a slight pay increase from time to time.
If you're worried about building products that appeal to the indolent and apathetic, just look at the entertainment industry, where actors and screenwriters work very very long hours to produce content that reliably keeps the indolent and apathetic entertained.
If you're just worried about diversity, I assure you that there are plenty of husbands, fathers, wives, mothers, and even single women, as well as both men and women of all ethnic and national backgrounds, who are diligent and conscientious.
