Your plan of action isn't inconsistent:
> Researchers seeking funding from the United States’s single biggest funder of the physical sciences will now have to think about how they can structure their own efforts to promote greater participation by researchers and students of color and from other underrepresented groups.
ie. If a well endowned university that was recieving DoE grants were to underwrite the expansion of education and scholarships programs at pre-K, elementary, and middle schools within their intake catchment areas to be more inclusive of people diverse in background,
then they can submit that activity as evidence of their efforts to expand the divisity of the researcher pool.
Granted it's an approach that takes years to bear fruit .. but it's the kind of approach that actually works and happens within the education sector of other countries that seek to lift all citizens access to education that matches their ability.
Of course, this smacks of five year (and ten year (and fifteen year)) planning .. so, communism | socialism. etc.
