Cardi B, a rapper and Instagram celebrity best known for her hit "Bodak Yellow," posted a video on Instagram yesterday where she asks some hard questions about effective tax rates and government spending.

B notes that she is paying a 40 percent tax rate and not getting much for it. She asks for accountability, noting that "when you donate to a kid from a foreign country, they give you updates of what they doing with your donation."

By contrast, B has no idea what Uncle Sam is doing with her "fucking tax money." She speculates about possible uses for government revenues, but points out that "y'all not spending it in no damn prison," because incarcerated African-American men only receive "like two underwears, one jumpsuit for like five months." B wants transparency, demanding "receipts."

The video has been viewed over 4 million times since it was posted late last night.

In her work, B has talked about her experience as an entrepreneur, explaining that after her initial success, "I don't gotta dance, I make money moves."
