I would have no choice but to call this an impossible task because of the fact that even you characterize this as a "livable fair wage." You see, once you introduce the term "fair" as an objective, I cannot calculate this without being un"fair" to someone for the reasons previously given.
Oh, I know, just remove "fairness" as an objective. That has been one of my principle points. You may argue for the "living wage" a number of ways, but you cannot argue that that it is an attempt at fairness.
Sure I can. It is more fair to pay someone enough to buy food, than to work someone 40 hours/week and not pay them enough to eat. (and live indoors.) First you tried to paint me as a Marxist. Now, you appear to be devolving in post-modernist deconstruction ala "Can anyone really define "fair." I guess I am slowly winning you over. Soon you will have no place to run! parsy.
