Credentialism has replaced merit as a selection tool. This is *not* A Good Thing™. They are not the same.
The author reinforces your point quite well:
“We would do well to leave room for the Lincolns among us—especially if they are as raw and uncredentialed as the man who would become our sixteenth president was. Think of his great speech at the dedication of the cemetery in Gettysburg in November 1863. As many know, there were two notable speeches that day. The first, and the longest and most learned and most florid, was given by the supremely well-pedigreed Edward Everett, former president of Harvard—and the first American to receive a German PhD. But it was the self-educated frontiersman president who gave the speech whose accents ring down through the ages. Perhaps there is a pattern here to learn from.”
