DEI. That is the ideal. We have never achieved it—ever—but we have always been working on it. Every corporation or business bound by these DEIs' inclusiveness is still a work in progress. Everybody in the workforce knows it. The time never came when Black people didn't lose jobs because employers needed to make room for whites who needed their jobs. I know all about that. I was a victim at least once in my career, but I saw it happen to others everywhere I have worked.
Employers can use any excuse they want to. For instance, Zuckerberg is a prime example of these employer types. The line of least resistance to justify firing a minority is either an invented work ethic, or ineptitude, which is a favorite, such as a Hispanic is needed for the position because the job now requires bilingual employees, among other things.
The sign that tells America that she has become a Jim Crow Era again will be if we see signs everywhere telling us we're separate but equal, Whites-only male and female restrooms: well-kept with plenty of toiletries in one area and, farther away from the whites-only area minority children will learn what it means when they see "Blacks-only Restrooms, coeds more likely than not. They will see us standing in lines to get food from eateries because Blacks will be relegated to the back of the building - where the kitchen is - and there will be only a few places to sit and eat a family meal. So, people will have to stand outside until a table is cleared for one more person or one more family to eat a meal.
As for other minorities, since they "separate" themselves from us to appear closer to the whites, I wonder where their restrooms and places to eat would be.
For anyone who does not know, Jim Crow was as demeaning and scathing as our ancestors' horrors were in or during slavery, by degree. No soul that is awakened to the Light of understanding would want to go back and live in the Jim Crow Era. That would be as demeaning for white people, Asians, Latinos/a's, First Americans, and African American Blacks as well as other Blacks/ethnicities in America. Some of us work together toward the same goals, and some don’t want to be identified with the struggle of the Black-skinned ones. Truth liberates.
