Final answer:
Barbara Ehrenreich's attempt to work a second job to pay rent is considered unsuccessful as her research in 'Nickel and Dimed' shows the struggles and inadequacy of minimum wage to cover basic living costs.
Step-by-step explanation:
Barbara Ehrenreich's attempt to work a second job to pay the rent can be deemed unsuccessful based on the insights from her book Nickel and Dimed: On (Not) Getting By in America. In her research, she finds that surviving on minimum wage is nearly impossible, despite individuals working multiple jobs, sometimes without days off, and living in extreme conditions such as in cars or being in and out of homeless shelters. Ehrenreich's experiences and observations highlight the harsh reality that even working multiple jobs does not guarantee the ability to afford basic necessities like rent, due to the inadequate pay and poor treatment of low-wage workers.
