Of course the rentiers can still squash things, and will. But I think the tide is against them.
Matt Stoller has done great work both documenting this and contributing.

This is not some "hidden history" -- they were quite proud of it. I watched it unfold in real time.
I find it fascinating that the Reagan administration (and the bevy of organizations around it) moved taxonomy and models such that the democrats (in particular Clinton) discussed economics and antitrust using the republicans' framework, just as the republicans still think of the economy from a Victorian/Marxist framework (Labor Theory of Value, capital expressed only in smokestack industries and finance, etc etc).
I'd like to cynically say that the rhetoric and arguments have finally started to return to their roots within this particular administration, but there's no evidence of a process actually being carried to completion yet.
