That example is correct, because in OOP you should not simply change state/value inside other object, because you pretty much end up with anemic domain model where classes are just structs and code that modify it is not part of the class. What parent meant was that you call "accept new job" on person object and then use this object instead of just setting the salary. Maybe it was oversimplified, though.

Yep, and that’s pretty much the simplest and most modular design for that problem.

This is one of the cases where OOP(whether using methods or messages) leads to more coupling and less flexibility.

I know what the parent meant. Your explanation now directly contradicts what the code does because even with the Job method you are directly setting salary except now it's a more circuitous way for the sake of abstraction. The person class has no notion of a Job.

MVC is not OOP (at least not what OOP was originally) and it's a shame that corruption of the idea was allowed to creep in.

I do like your use of the word "anemic" to describe the method free classes that pass for objects these days.

What you are referring to our container classes which exist solely to hold members. This is not that case. The setting of salary is one of many behaviors offered by the class.
