This question has been bumped from time to time and i'm here to answer it
why is spongebob proud of minimum wage?
Well, as quoted by him in "Employee of the month" He teaches the true value of hard work
"Squidward, having pride in your work is nothing to be ashamed of, why it's the only thing that makes it all worth while"
I think that was a very wise quote, that's really overlooked
What's the point of having a job if you don't take pride in it?
So thats the reason that spongebob is actually a good example and not a bad one.
