Before a revolution (in any sense) can be sparked, it's necessary to figure what, and for whom, the revolution is. In a nation as profoundly divided as ours, the old "99%" theme defies all logic.
On poverty, yes, Sen. Sanders used to speak out powerfully about poverty and the need for legitimate poverty relief. (It's impossible to save/rebuild the middle class without shoring up the poor.) Since Bill Clinton threw the poor off the cliff, liberals have stood in solidarity with the better off alone -- workers, preferably middle class. That's just the way it is.
We have a poverty crisis, not just a low wage problem. We already tried decades of calling for jobs. Looking ahead is good, but we must also deal with the present. Not everyone can work (health, etc.) and there aren't jobs for all. The US shipped out a huge share of our jobs since the 1980s, ended actual welfare in the 1990s. You can't get a job once you no longer have a home address, phone, bus fare. What do you think we should do right now about all those who are left out?
