That is assuming the fax repairman has the motivation to do all of those things you have mentioned. Considering that life ideally leads to a comfortable retirement for most individuals (i.e.: doing nothing and spending one's days leisurely is the ultimate goal as opposed to creating value for society). I think it is safe to say that most people, given the opportunity, will opt for this "lazy" style of life.
Now I'm not saying this is inherently a bad thing. When technology and automation improves to the point where laborers are made obsolete, could society potentially adopt an egalitarian system where through taxation, society can afford to let the laborers live in complacency with a satisfying slice of the pie, while the more ambitious (those who continue to push through with scientific and technological advancements) are rewarded with an even bigger piece of the pie? With increasing advancements, will society reach a point where there's more than enough pie for everyone?
