Critical Race Theory has value in understanding how policies can unintentionally promote racial discrimination. Its application belongs in the court room and teaching how to use it to make a case in court belongs in law schools and not in the classroom of children, where poorly trained teachers and in some cases, students attempt to apply it outside of its limitations as a theory.
Its purpose is to challenge actions that potentially violate the 14th Amendment, not to promote equity. Equity is a value concept and ideally should have no racial component. I don't believe in "equity" as a societal goal, but if one embraces it as a societal value, it should apply to every individual and not be allocated based on race. If ten rich white people and 100 poor white people comprised a population which included 11 poor black people, you don't achieve equity by selecting one black person and making that person rich... you have simply changed the outcome from 10 rich people and 111 poor people to 11 rich people and 110 poor people.
Like any "good" thing, CRT can be corrupted into a bad thing and if history is any judge, it will be. The primary source of this corruption is people engaging in what is sometimes labeled as "Applied CRT".
