I'm just taking money out of the equation, which means there will still be a lot less jobs to do, resulting in way less work load.
Of course machines need to be produced and maintained, but only a fraction of what we build now, and as there is no reason to exercise planned obsolescence or nibble on the costs by choosing inferior materials, these machines have a way higher quality than we make now.
Another difference is that whatever work is still done, this will be done by people actually wanting to do this, out of interest and passion.
