I feel like this question has been discussed and worried about before in our history. Not to say it is not worth discussing again, I am interested to hear the opinions out there. I remember when car manufacturers began to automate, everyone worried about job losses, but the truth is if we had not automated somewhat, we would not have been able to compete in the world in that industry. Businesses completely shutting down lose more jobs than bringing in some technology to replace some employees.
My one fear is these layoffs creating an environment, even more than we have now, of haves and have nots. Maybe there will be increased need for servants in households of the wealthy. Maintaining the grounds, maid, nanny. I also think there will continue to be an increased need for child care. There are other industries that will create jobs. I truly believe the solar industry, if we can get that going, will have jobs for people producing and installing solar, it could be big; windmills too. We do need to continue to build and maintains our infrastructures, so those jobs continue to grow, and are not done by robots. Even surgeries done by robotic tools need to be done with a surgeon in the room, although maybe the need or nurses in the room is cut down? I have no idea.
I think one positive that is coming out of our economic struggles and unemployment is an awareness that living beyond ones means is not such a great idea. It saddened me that we got to the point that to live in the nice safe neighborhood in a great school district we had to spend a huge amount of money on a house. I am not even talking about inflated house value, but more about having to buy larger homes, homes with more than we would ever need. Americans, well I think anywhere in the world, but I will talk about my country, Americans should be able to live a comfortable life, with a moderate income, moderate spending, and have a safe place and good schools for their children in my opinion. We were getting to the point where people had to spend more than they could aford just to live in a decent neighborhood. If we can get more reasonable in our spending, we can have more options, more options for a flexible worklife, more flexible about staying home with our children for a few years, more flexible about taking a year off and travelling. I hope we move in that direction.
I love @Simone_De_Beauvoir idea of returning to the farm more, being in the outdoors, with the land. Less massive industrialized farming, and more local growers. The idea of us moving towards more self sufficient communities again, but still interconnected with the country and the world.
I was a little all over the map in my answer, I think there are many possibilities, I was just writing whatever popped into my head.
