No it isn't. If you assert that a 32 hour work week decreases the amount of labor production for a given individual then you are asserting that less production will correct the problem of decreasing production. If you assert that a 32 hour work week provides the same amount of productivity, then it has nothing to do with the problem at hand(but I grant that such an assertion isn't proven to be a false claim, in fact I've seen merit for that argument). However, either way this is NOT an argument in favor of that.Less production does not solve economic problems. Better direction of it through the correct incentives does.
