Using that logic, a PhD oral is an entry level exam - it allows entry
into the ranks of those with PhDs.

As far as I know, there is no governmental PhD class
license and therefore no governmental ranks of those
with PhDs.

An amateur
license is not a status symbol. Its only worth is the
privileges granted. In the 1950's, generals, conditionals,
advanced, and extras all had the same frequency privileges.

Except that there were no advanced class licenses, and the extra was a
prestige license.

You don't seem to know much about 1950's ham licenses.
You didn't know that Conditional was a General exam
taken by mail. You don't know there were many Advanced
class hams in the 1950's faithfully renewing their
licenses. My Elmer was an Advanced licensee. Here's
a quote from a 1957 ARRL License Manual: "Holders of
Advanced Class licenses may renew them so long as they
can comply with renewal requirements."
