Moral dilemma about work
If there is zero need for employment, unemployed is the natural state. Imagine for a second all workers are replaced by self fixing machines. Everything is provided to mankind. You could not possibly get a job that was necessary. There would be no incentive to deny someone getting fed.
Before society you could hunt for food and feed yourself, the need for you to do that was 100%. As society evolved people divided into roles in a way that it increased production. Inventions accumulated to where production got so high there was nothing to do. This caused the emergence of the health industries, which further improved productivity. And not necessarily industries like service industries and eventually entertainment industries arose. We don't need these, but we want them. More and more jobs are now being replaced by machines. The accumulations of inventions continues, so eventually the amount of necessary work is trending towards 0. Like in a hypothetical scenario where machines do all the work.
The need for work is smaller
As we are somewhere between this utopia of no need for work and the "living hell" of the past. We do not need 100% work participation. Nor can we afford to have to many people not working. If we don't have enough necessary jobs for the people to go around, we cannot expect everyone to have a necessary job. And if we want everyone to take part in necessary work, we would have to split necessary work into smaller portions.
Should people feel shame they are not needed
If there is no more necessary jobs, can we expect people to have unnecessary jobs to be allowed to live? If they are willing to work, apply for jobs; but they are not hired. If there isn't any need. Is it really their fault? I think the fault lies with the ones distributing the work. Everyone can't become fingernail painters? Do we deserve fingernail painters? I say no. Our leisure is not worth more than theirs. I say we have no right to withhold basic needs when we have a surplus of it. The work done by the machines, can benefit the everyone.
What can you do if you don't have a job
There are other ways you can contribute, by doing volunteer work, arts and helping others. If you own a house you can refurbish it so that it is more worth to society, you are not going to live there forever. As long as you are doing what you can, nobody can really blame you.
