My gripe with "living wage" is the term (to me) is too subjective.
MIT's living wage [0] seems to include car ownership (despite King county having a decent public transit system and I know several people that don't have cars working in tech). My first place in a great part of town was $1,400/mo in a roomshare. The podments are as low as $750/mo, but MIT says you need at least $2k/mo.
I'd love to know if that is a livable wage in King County.
