As time goes on, and technological abilities improve, more and more jobs will fall to "robots" or computerized replacements for real jobs. There will always be need for creative jobs, engineers, etc, but the non-skilled labor jobs will be less and less. I don't see how anyone could disagree that there is already a problem here, and in the future, there will be an even bigger problem. The only people able to get jobs will be educated/skilled. The lower class will grow lower and lower. Aside from that, in the "old days" women stayed at home and took care of the family. "Nowadays" women are going to work, and I think that is absolutely great! However, that is more people working, therefore less jobs available.
I'm sure we'll come up with a solution. Although I think the first step is admitting there is a problem. Innovation will come, it will just take time.
Imagine a self-sufficient world far more advanced than ours. Imagine a world that practically runs itself and leaves us to care for each other and blossom with nature. The only problem is, this imagination world would never be allowed by multinational corporations and big business. Wealth would be more evenly distributed, they can't have that.
