Fast Food pays sh*t. She should go to bartender school. She can earn a lot more with tips and such and those places always need day workers. She can also waitress and earn way more. Fast Food is for high school kids. But even at Fast Food she can go and become a manager and earn around $40k per year. Her being poor is on her. There are ample opportunities to get out of poverty. She can also choose to go to Home Depot and learn a trade.
She doesn't have the right guidance. Period.
