Those students _are_ focused on wide reform in _every_ field. The article and those like it are cynically composed to describe only racial reform efforts in order to drive a wedge between white and non-white working class voters and to demonize the few wealthy who are actually on the side of reform.
Indeed it is the very group doing the anti-racist protests that are the ones _allied_ with economic reform. That's where the Bernie Sanders supporters are. The problem would be the polar opposite students in Yale solely there to learn how to increase hereditary wealth and power.
These exact same techniques and even words were used in the 60s to demonize economic reforms by railing against the "extreme" behaviors of student then. Portrayal of universities as Communist (still a common theme on Fox), focusing solely on pro-integration and anti-war protests to falsely portray disregard for white poor and national disloyalty. They kept two out of three today.
And they found they same audience to stoke the same unjustified resentment then as now by falsely convincing working class whites that powerful liberal economic reformers are only interested in non-whites. And so drove a wedge between working class whites and non-whites. And so Nixon and Trump.
The catastrophic rent seeking and inequality is certainly _not_ coming from those few privileged students who publicly disapprove of that. The one involved in dramatic reform protests (that includes but are not limited to racial items). There are zero students in those protests who oppose dramatic economic reform. The problem is from the actual people causing it: the Koch brothers, the Waltons, Murdoch, people who don't get remotely as many outraged articles as these students.
