There aren't enough jobs for EVERYONE to be employed though. The number of unskilled jobs is going to shrink as automation and efficiency increases. Also, not everyone is capable of working, like the disabled etc.
There will always be enough jobs if the government is paying. It may not be something that's worth what the recipient is getting paid, but there's always something to do. Picking up trash, road work, landscaping, sorting trash for recycling, etc.
Also, most of the disabled are capable of doing something. A guy in a wheelchair can man the desk at a library, for instance.
