We are now entering a new age where our current form of capitalism will not work. You see, when there was enough demand on the workforce (as in, there was as much or more work to do than there were workers), things worked reasonably well. Now we are entering an era where there is much less demand for workers, yet we are not yet productive enough to just sit back, relax, and let machines handle 99.9%+ of the work.
Think about it: 50% unemployment is terrible. 100% unemployment is not unemployment. It means there are enough resources to go around that nobody has to work. There is so much food, shelter, and entertainment that we don't need to get up in the morning and go to work.
Obviously, 100% unemployment cannot happen. In all likelyhood, we'll still need doctors, chefs, artists, etc. But that the direction we are going in, and we better figure out how to set up a new economy to adapt to the new realities.
I envision a shift in the mind set. Personally, if I have more money then I could spend in a lifetime, and choose to work to make myself even richer, I don't care if 10 other families are living off my wealth. People will have a choice: do something productive for society, and live a slightly better lifestyle, or pursue more personal fulfillment. We'll see a lot more artists, and a lot less custodians. In the long run, I believe this shift will be a good thing, but it will require us to stop using terms like "moocher class".
