Also we don't have to conjecture very much about it, since Mongrel's pointed out that affected industries are already flipping their goddam shit. The future is now.
I think the real question is how concerted the opposition will be.
For a long time, Big Media presented a very solid collective front. They still are, but now there are some heavy hitters on the other side and of course there are some who straddle both sides at times (Microsoft, Google, and yes, even Apple).
"Everybody who manufactures cheap/middling stuff" is a much more widely dispersed group. That's not to say we won't get a united front, but it wouldn't suprise me to see much greater fragmentation either. Many companies already take advantage of the "Prosumer" - making the customer do the work (from ATMs, to self-serve websites/checkouts, to whatever else).
I can easily see companies getting out of manufacturing and just selling CAD/CAM design files. Or new companies opening that just do this. There's a
very low barrier to entry there, so we could see some real giant-killer situations.
Sure this means even more jobs lost, but it looks like the world's going in that direction anyway.
