There’s a scene in Django Unchained where he’s telling his friend/mentor Schultz about his wife Hildi and how ‘she ain’t no field [worker]’. But ever since they got caught running away, branded, and separated, she’s most likely a “pleasure girl” now. The big difference here is that Nicki has full control over her actions (and freedom) yet she chose to put herself there. Hell, she’s rich enough to just keep to herself, keep her mouth shut, and happily retire. No one asked her to do this
