This is all virtue signaling. If they really cared about stopping discrimination then they could change it from being a civil issue to a criminal issue. Right now if someone is discriminated against they still have the same old two choices; either they ignore it or they sue. Suing anyone much less a company with deep pockets costs a ton of money and in order to win there has to be a "smoking gun" or a mountain of evidence to prove there was discrimination. And the problem with collecting that evidence is that such discrimination usually happens in person and without any written evidence to show for it at a later date.
Video evidence of personal interactions is very hard to collect in Washington state because it is a "two party consent state"[1]. And people's personal behavior changes when they know they are being recorded[2][3].
I think a better solution to this is to get US Federal "Title VII of the Civil Rights Act of 1964" updated[4] to include caste based discrimination as that will bring this issue to national attention and hopefully enable other people that are not being directly affected by this discrimination to be cognizant of it. Once enough people become aware of the problem then it will start changing the US culturally and societal accepted behaviors which is the only real way to stop this type of discrimination. Of course while dreaming of a better and brighter future I might as well add the removal of all cliques to the list as they are another form of discrimination.
