Ok I just have to ask, what do you consider a Living wage? It can be yearly or monthly? Do you earn towards retirement working part time?
We have a whole class of part time workers that have college degrees called Substitute Teachers. They do not make what a full time teacher does so with the exception of what Roodie posted about health care workers I don't believe education is at the forefront of wage equality. Here is a quote from one such teacher and a link from a source the more socialist leaning members should approve of. It also might be a reason many of us are not as impressed with your calculator or the assumptions on quitting a full time job and looking for one just across the street.

Here is a quote: a week of working in an urban district, a teacher could expect to gross around $400 on average but take home around $350 or so after taxes. Assuming work in that district, everyday, with no snow days, holidays, or vacation days, that would amount to $1400 a month, on average. One can assume $1400 * 9 = $12,600 as a yearly salary in substitute teaching, but you have to take into account the times of the year when teachers are not taking days off. This includes the beginning and end of the year, around the holidays in December, the days surrounding winter and spring Break, as well as random holidays when there is no work: Veterans Day, Columbus Day, Jewish Holidays, etc... So take away a month to two months and you have a take home pay, for a full-time substitute teacher with no benefits of $9800-$11,200.
