That has nothing to do with ethnicity (Hispanics are not a race) and did not occur in TX, OK, and ND.
TX, ND, and OK did the same production cuts VZ did in 2015-16.
Yet, you aren't calling them incompetent, even though they did the same thing VZ did...cut production.
WHO was doing the cutting didn't matter; what mattered is the big picture, which was a price war that was being waged.
