Brownfield apparently has had enough of a certain political faction - the Shapleighistas - as being referred to as "progressive".
In his eyes, Shapleighistas ties to their so-called corporate masters does not make them "progressive".
Real progressives are folks like FDR and LBJ. Brownfield mistakenly refers to Vermont Senator Bernie Sanders as a progressive. Sanders is a self-identified "democratic socialist". Unless "democratic socialist" and progressive are one-in-the-same.
What Brownfield, may or may not know this, but "progressives" need rich people and huge corporations. Those are the folks and entities that can help prop up a progressive form of government.
LBJ knew this. We may know LBJ for Vietnam and the Great Society, but you may not know him for helping KBR become what KBR is today. You know...the KBR that so-called progressives railed against during the Bush years.
Labor? Labor needs large corporations. Organized labor is often found in industries where there is little to no competition. Labor's goal is not to kill the host. Killing the host is what happened in the former USSR and host of other countries. Labor cannot live off "mom-and-pop".
Despite what Brownfield says, the Shapleighistas are very much progressive.
I think he's just mad that he does not get invited to the parties.
