It would be an awesome first step if we could all just agree that the middle class (at least in America) is in decline from what it was one generation or two generations ago, and that that has several bad consequences, and that we should try to think of ways to reverse this trend.
I think it would be reasonable to admit that it does look as though a lot of currently-existing good-paying jobs (and even notso good) are being automated away, and that we don't really have much sense of what jobs all those displaced workers might be doing a decade or two in the future. I can easily google up lots of examples of current attempts at automating away whole classes of workers - bus drivers, teachers, care-givers for seniors, farm workers, guards and night watchmen, legal and actuarial staff. Logically, if the costs per unit output were more for these automated methods, (once the design, support, IT etc was included) than for the labor-intensive solution, then no one would be pursuing them. I don't see anything in recent economic history that leads me to believe the higher profits yielded by these automated techniques will be shared with the remaining workers. I doubt that too many of the displaced bus drivers or farm workers are ever going to be retrained as robot maintainers (or whatever new jobs are created.)
Most likely outcome: management is going to develop and use automation wherever it can, let go as many workers as the automation allows it to, and keep the profits. Productivity goes up, but the remaining workers don't get much in higher wages. Economic value (e.g. money, capital) continues to be concentrated at the top of the economic pyramid, where it is stockpiled and rendered useless.
