Well, let's look at the macro model of agriculture. Do you need to work from 6am to 7pm, doing difficult manual labor, in order to feed yourself? No. Automation replaced farming, so now you can do much simpler and easier work, and still get enough food.
Transition from the Argriculture -> Industry -> Services was discussed a lot of times above, as well as assumption that there is no 4th sector after "Services".
How about the macro model of manufacturing? Do you need to work for weeks just to put together a car, or some other gadget, or pay close to $100,000 just to buy a car? No. Automation replaced most of the manual labor required to manufacture goods, and now you can do much simpler and easier work and still get things like cars and gadgets.
Do you see where the trend here is? Less work, and simpler work, to get the same type of stuff that required a lot of back breaking labor just a few decades ago. In the future, you may be able to afford food, a car, and whatever else you need, just for the labor of wiping down some robots with rags, and replacing a few screws.
I am wondering why some people still believe automation will make anything "cheap as dirt"! This will never happen because your fundamentalist faith in the free markets is just a pure theory having nothing with the real world where do exist monopolies, patents, cartel agreements etc!
