I wonder why

My niece’s dream is to work abroad to help her family. So she studied Accountancy, because she think she will earn a lot of money once she become an accountant someday. After eight years, I happened to talk to her mother  in the province. And she told me that my niece is now in Canada, working as a Care-giver. What happened, i thought she aims for a finance jobs but she landed to be a Care-giver? Then her mother explained to me the she shifted to Nursing because of the demand abroad.  And she even told me that getting enough salary of being a Care-giver, my niece already even forgot to get married. And we both laugh out loud together on the phone.
