They do become master in the end. One of mine did

Well I am a Registered Nurse and I make $450 per 12 hour shift..and I only work 13 shifts per month..and I don't get to work from home and take breaks bar-b-q-ing..and get paid 7 days a week..I guess I should go back to school to be a shoe maker *LOL*

Some of the jobs - and *many* of the names! - are silly simply for the fun of it, I'm sure.

There ARE teachers in the game! Okay, they are named Tutors, but comes down to the same, right? Guess Tutors can work from home more easy than teachers. Although on-line education is a real thing in real life, too.
I've had math-tutor and a history-tutor.
Not the best payed jobs (as in real life) but I was happy with it, since I'm a teacher myself

I have an english tutor also.

Almost all of my peeps have become Masters...even Emma who had 6 kids! She's 63 now and I'm dreading the day she passes on. You've just got to praise them for working and every now and then let them do something else to keep them happy and healthy!

One thing about the careers I have laughed about is when generations change over, you've got kids that all went to college, and they have careers like "spammer," "hacker," and "silverware polisher!" My RL father would have demanded his tuition money back if I'd come out of college with a career like that! On the other hand, I've seen a fair number of rocket scientists, lobbyists, and such as that. They start out earning really good money ($105) but I've found they're pretty lazy and don't go very far in their careers.

You're right about that!
Some of the more hands-on/labour intensive jobs becomes the best paying jobs. My Pesto Sauce Creator, @ Levl 5 earns $174. I believe his starting salary was $15. His lazy wife, mother of 2 children, and Vitamin Inventor, has yet to complete Levl 1.
