Nonsense. For instance standardized testing wasnt created to discriminate against blacks, it was created to measure competency. Such testing was implemented in lilly white europe 100s of years ago to differentiate competency among whites. Has nothing to do with race.
I never said standardize testing was created to discriminate against blacks. the point you quoted was about a historical adoption of what people called "culture" that was based on racism, build upon premise of segregated society where whites were in the dominant avenues of economic, opportunity, accessibility and social considerations in general and non general society.
As to Testing:
China actually learned something about "testing" because they long relied on it within their rote memory styled education system, they discovered and it was noted I think around early 2000's or in that frame that "test scores did not translate into higher productivity". It's so unfortunate because we left the system of free thinking, and adopted a system of rote memorization for the sake of test taking, and we called it measuring competency, and what we did was stifle creativity and introduced boredom into the schools systems, then we took out civics emphasis and left that up to folklore which adopted partisan promotion, rather than the civics of American Democracy's principles and its governing policies and values. kids can no longer pose the questions of who, what, when, why, where, and how come... they are deemed to be taking the teacher off the programmed lesson plan structured for "test taking" so they are reduced to a generalized form of rote memorization. Today, kids are tired of it, their natural instinct of critical investigative thinking is now resurfacing and they want the truth, and they won't settle for less, about "anything"....
Party Power became more important than Political Intellect. and Money rained to the wealthy like someone busted a dam.... and the gap has been widening every since between what is wealthy and what is working class middle class.
The pay to get a degree led to "degrees costing more and paying more' but requiring less and less integrity, principles, character, dignity and ethics.
So, the point is, that CRT... will reveal a lot more than just about black people, but much about white people and the system and society and how it became what it is. which is inequitable to the general population.
We are still paying people $7.xxx in a world where companies are bought and sold for $Billions, and profit are measured in $100's of million up to double digit billions, and Minimum wages is pegged at what it would cost in today's valuation to house and feed a slave, or pay an poor white during the era of slavery.
jobs that were done by slave, and poor whites.... are today, still jobs that are ill respected and underpaid, but they are critical to the society that expects those labors and services.
