To the contrary -
Repeated attempts at have been made at all levels to try and deal with the discrimination suffered by the various racial groups, but no matter how much people try you can readily find folks who still want more. For example, Corey Booker and a few other Democrat candidates for President have said that if elected they'll force the government to pay reparations for slavery.
How is dealing with discrimination maintaining the same laws and practices that estranged and literally separate discriminated groups from their family, the free world and other systems afforded to non-hyphenated Americans. Are you trying to convince me there is no racism in America in 2020, and if there is it is the fault of the hyphenated Americans? Let's get to what the point is, because I am not debating 20 pages of American plea for social and economic relevance in the form of arguments for superficial "change" - especially in the opinion of the entities who turn blind eyes to the oppression.
Saying "stuff has been done" is ignorant - it is a position that literally ignores the "stuff" would never work, and that it was an insincere attempt in the first place. Realistically I don't expect anyone benefiting from a privilege to demand it to stop.
Meanwhile, other groups who suffered
False equivalencies marginalize efforts of equality, and increase resentment by ignoring the affects. That is a psychological issue, also.
- such as various religious groups - have been rather consistently ignored or even mocked when they bring up the concept of government actions against them being squared.
Why do Americans think what is going on is religious oppression? Have Americans been to China, or Korea, or even the middle east? Have Americans been murdered on a daily basis for their beliefs yet?
I think very few Americans are ready to die for their god, and they are definitely not willing to die for something outside of their "tribe" and "totem" - which usually has self and circumstance at the top. Perhaps this misunderstanding in religious oppression and anthropology is a reason why people may believe "stuff has been done" to assuage prejudice and racism in the States when it should be clear the prejudice and racism has simply been
telegraphed to a different vector of entitlement.
Hyphenated Americans are still sitting in jail innocent after decades of false assusation projected by hateful people who
could get away with it. Hyphenated Americans are still being beaten and shot in the streets, but recently it seems there has been an accidental spill over onto other groups that matter.
Nothing has changed about America except the psychological application to tyranny and exploitation. The irony is the people who succumb to faceted discrimination are already being exploited without their knowledge. Everyone plays a proper agent of history already written - this time it is the history of the States.
