They won't be kicked out onto the street, or forced to give up the pleasures of life. There will be no poverty. People will have to work, but it will be voluntary.

Work is part of human life.
Today rich people work when they don't have to, because they, like many of the rest of us, enjoy working. Many people work harder at their hobbies than they do at work. Work needn't be a part of the day that we wish would end. People enjoy creating useful things. Instead of producing junk that people only buy because they can't afford quality, every worker will be able to produce quality products for themselves and others, and know that other workers will be doing the same.
