I don't disagree with the substance of your comment, but it's worth pointing out that Alphabet is a company with a $1,416,000,000,000 market cap.
If any non-governmental entity could be said to have the resources to address "systemic issues" at the root, it would be these giant multinationals.
If Google wanted to, it could fund CS education in primary and secondary schools in black neighbourhoods, it could launch a finance wing to offer mortgages to families disadvantaged by a history of red-lining, it could endow scholarships at HBCUs, it could invest directly in infrastructure projects in majority-black cities...
Obviously there's no obligation for them to do these things, but if they cared to really make a dent in America's racial issues (instead of just making white folks feel more positively about Google) they are not lacking the capital to take a stab at it. They certainly don't mind pissing away millions on internet balloons.
