Sandwichman — "I’m not sure I follow the arithmetic here."

All of the above, of course, is simply the fleshing out of assumptions. We assumeddiminishing productivity in the last hours, we assumed heightened productivity from a shorter working week and we assumed declining marginal utility of goods and services produced. Finally, we assumed a preference for free time over a vanishingly small increment of total income. The point is that each of these assumptions were relatively modest but when combined "add up" to a rather substantial cumulative result.
