My question is the following:
Let's say a person has two career choices. He would be succesful in both, but in one of them he is slightly better and thus he will do better. So let's say career A will bring him a utility of 10 and career B a utility of 9.
So career A will bring him a 1 net utility benefit, due to the opportunity cost of 9 of pursuing career B.
Now suppose that for whatever reason, career B is not a choice anymore for him.
Is he now better off, from the fact that his net utility benefit is 10 and not 1? Why or why not?
