A good portion of modern day activism does take this "macro" approach by extending the scope of activities further and further for those disadvantaged. There will always be a focus on those more disadvantaged groups, firstly because of the immediacy of their problems, and secondly because of the fact that it's hard to get people to share the same set of aims about society as a whole.

In the second half of the 20th century, many (most?) of the movements for anti-racism were also linked with feminist (gender) and socialist (class, or from another angle, your macroscopic vision) movements, and nowadays most such movements are intersectional anyway. I think that's a good thing, while there are good critiques of intersectionalism, even the critiques favour approaches that leverage immediacy and universality.
