amelia wage slavery and frederick douglass

Amelia, a worker in mid 19^th century Lowell, Massachusetts, claimed that factory workers were caught in a system of “wage slavery.” How did she justify this claim?

Using what you know of factory work in mid 19^th century, explain how such paid work might compare to slavery as described by Frederick Douglass in his Narrative. (Remember to frame this discussion in the changing context/s of the time period.)
