It doesn't include those things because those aren't the things that are covered by a "living wage". Living wage sounds like something good, but it's literally just enough to cover what's needed. Can you afford housing, childcare, medical care, transportation for work, etc. It's a low bar, not a good target, for a society to try to hit. It means people at that wage shouldn't be going hungry or without shelter, but they won't necessarily be thriving.
