I have mixed feelings on this. For starters, I seriously doubt it could even be stopped. Technological progress is unavoidable and has numerous benefits. Everything is cheaper and better than ever before. "Classical poverty" is basically nonexistent in the western world, that says something.
I don't think people "need" to work. I think it has been the case for all of human history, but I don't think it will always be that way. I really believe that in a hundred years we will be in a post-work society, for better or for worse it's going to happen.
I think it's the most interesting question existing today though...what happens when unemployment for high school graduates is 40%? What about 60%? It's a scary thought. Off the top of my head, I can only see the trades, mining, etc being real jobs in thirty years. It's pretty tough to automate an electrician or road pavement. But women are huge minorities in those fields, what do they do?
Economic oligarchies do have benefits. Simple Economics of Scale show us that. As long as proper competition exists (and I don't think it does in the US), it's not a bad setup. It's important to recognize that small businesses aren't totally eliminated, it's just that the markets are bifurcated. Small niche companies exist, and the huge corporate behemoths dominate the market. In theory, that's not bad. In reality, lobbyists make small business a bigger struggle than it should be.
Lastly, its also important to recognize that the big corporate behemoths are constantly crushed, too. Where is Kodak today?
