I don't think that's so clear cut. Griggs is the direct reason for the popular wisdom that you need to get your college degree if you want to have a good life. While some college degrees, as they ever have, confer on their owners a mark of distinguished ability or knowledge which does directly improve your life, Griggs had the reverse effect on the margin. If you and a person with no degree apply to become a hairdresser, Griggs provides you with potential legal recourse against the company if they hire the person with no degree instead. It's probably pretty rare that anyone sues for this reason, but it's common enough to have changed corporate hiring policies all over the nation to force the hands of managers in some scenarios. The popular wisdom should really be that you need to get your college degree if you don't want to be ejected from the economy, because in many cases nobody will consider your skill set if your credentials don't make that justifiable, but you say tomato, etc.
Griggs is the underlying reason there's such a rush for the marginal students who have no interest in education whatsoever to get a college degree. Sure, there are federal loan programs and myriad other policies and laws that help them get there, but the whole problem really follows from the distortions created by Griggs. IMO, anyway.
