It wouldn't if we all had enough resources to get by on our own. We should be looking to automate as many jobs as possible and thereby provide everyone with their maximum amount of free time.
I'm half-inclined to suggest automated job assignment, too; I'm pretty sure Google or Facebook have enough data to accurately find people jobs. Yay surveillance!
Grats! Being on the job market is one of the most disgusting and pathetic experiences one can expose oneself to - solely because of the nature of markets in general. The same is true of other markets that have you sell yourself as a person: the dating market, slave market etc.
