It doesn't say she left her previous employment in order to take on a job for less money, it simply says it paid less than her previous employment. For all we know she could have been out of work for a year between, trying to get a job. Saying someone accepted a job at a miserly rate doesn't make the rate acceptable. We don't think paying immigrants a fraction of the minimum wage is acceptable, we don't (any more) think that expecting years of unpaid internships is acceptable, and we don't think that the jobs the factory workers first started to unionize against, with terrible wages and unsafe conditions were acceptable, despite all those people "voluntarily" accepting the jobs. Having a job isn't just "voluntary" for most people. The pressure to have one in order to survive, plus the difficulties, costs and risks associated with switching, gives the employer power over the employees.
