None of those concerns were relevant in the era when the Civil Rights Act was passed and people were hired via face-to-face interviews. It's real hard to hide your demographics when you're talking to the interviewer, which is a much larger concern than whatever you put down on a piece of paper.

For all the talk about it in this thread, we aren't moving to some kind of double-blind anonymous voice muffled 60 Minutes interview screening processes anytime soon. It's a goofy idea because once you hire somebody, people are going to work face-to-face with them anyway.
