There's a strong possibility that technology in the future could create a massive wave of unemployment - as people are replaced by smart machines. Of course, life could still be better overall as these machines could provide for all the necessities for the unemployed at a low cost. So the unemployed would be more like retired people. The big question is whether people will merge with machines or whether they will be distinct. If they don't merge, the replacement issue is much more likely (with high unemployment). If there's a singularity a la Kurzweil, then the problem is moot.
