I recommend Jason Furman's work for the practical mechanisms by which unnatural monopolies can be broken up and natural monopolies can be regulated. On the other hand, you are interested in why the status quo isn't an accident and what we would need to do to accomplish those things, I recommend reading Reid Hoffman's book "Blitzscaling" side-by-side with Jacob Hacker and Paul Pierson's book "Winner-Take All Politics": you can see the same dynamics presented in two very different lights.
