There's a lot more than her aunt standing in the way. Emancipation is not something that you can just go out and get. Unless that "small job" is sufficient to pay for 100% of your friend's rent (market rate, not a token for living in someone else's home), food, clothing, utilities, transportation, medical care, insurance, staples, school fees and supplies, and she can earn enough to pay for all that while still going to school and getting better than average grades, emancipation is not even an option.
