The merits of our own productivity/leisure ratios notwithstanding, do you really want to exist in a society wherein "productivity" is the ultimate and totalizing end? Do you not think we should striving for a society wherein all folks have some (we'll leave quibbling over the exact amount for now) leisure time/space in order to cultivate interests outside of their capitally "productive" selves?
No, we must all make our masters more money so they can find a way to suck more out of us and ultimately send our jobs overseas.
