I can understand why you think the video is tone deaf, but do the people appearing in the video agree with you? Do the millions of Democrats who voted for Hillary in the primaries agree with you? I wish the Democratic party were a lot more progressive, but all those Democrats who chose Hillary over Bernie tell me it isn't, so there's a big part of the problem right there.
I don't think any of us can really understand what goes on in the halls of government, and I don't know whether Obama was bought, was being pragmatic, or was just wimping out. I give him some benefit of the doubt simply because I haven't walked in his shoes. I can complain about corporatism as good as you, but big money is apparently what it takes to get elected, and until campaign laws are radically changed nothing else will change.
Well, do obstructionist Republicans deserve some of the blame here or not? I'd say at least half, so my anger with them is at least as justified as your anger with Obama.
