There's really three titles, right? Bachelor, master and doctor. To me, the first was always the weirdest if the bunch, and if we're renaming things, maybe we could confer the hierarchy of the titles?
What's a good synonym for mastery? How can you describe someone who has mastered something? Expert, OK. What else?
In the US we've got 12 levels (years) of primary and secondary education, followed by 'higher' education. Here at least I suppose you could call a bachelor's something like "16th grade", or "Level 16". Different Masters and PhDs require different numbers of years, though, so it's not a great system.
How about something like "Practitioner" instead of Bachelors, "Expert" instead of Masters, and stick with Doctorate for the PhD?
