94% of Jobs at S&P 100 Corporations Went to Non-Whites After Black Lives Matter Protests
Personally, I don't think this is about race. When I worked in a factory with a very diverse population I think it was encouraged so that there was little likelihood of us seeking to join or create an "onion" (The word is actually rarely spoken by me, because of how much real ones would be attacked.)
Professional jobs may actually get replaced by "machine learning" even more quickly than blue collar ones, especially if professions like medicine allow "standards of care" and/or protocol to take the place of human interactions. If your work force is diverse and immigrant, they will be unaware of rights protected by the Constitution and they will also be more vulnerable to displacement by machine learning.
