Bookkeepers, lawyers and healthcare professionals require very specific and specialized training and in many cases it is not even legal to be employed as, say, lawyer or doctor without having specific credentials. But many jobs aren't like that - and still require degrees.

For some jobs - definitely. But there are plenty of others where degree is just a very rough filter and degrees that do not provide any direct training for the specific job are still required (and accepted).
