You may never have heard of Chief Dull Knife College, but it spends almost as much for each degree it grants as MIT does — $309,000 vs. $341,000. In a dismaying story, Tom Burnett, a retired Montana legislator and businessman, describes tribal colleges. Mostly created following a 1978 congressional act, the 35 colleges attempt to train American Indians for jobs on the reservations and, at the same time, preserve the language and culture of the various Indian tribes. They aren’t doing a very good job of achieving either goal, in spite of the high cost to the taxpayer.
