I think if you look at the entire history of the US, you'll find they've been going after Black people real hard the entire time, and that the root of mass incarceration was as a direct replacement for chattel slavery while the ink on the abolition of that institution was still wet, focussed on Black people, who have been vastly disproportionately its target ever since.
I think if either group had a less docile reputation they'd be gone after far more surgically and in far lower volume.
