The following site breaks down the living wage required for families of various sizes, and the wage of various industries.
I compared the living wage for my own family size with the average wage per industry and realized there were only 3 industries I could earn a living wage in, management, computers, or legal. Fortunately I have experience in the computer industry (surprise HN).
Let me spell it out. The following industries provide a below living wage, on average, for a single parent with one child: business & financial operations, architecture & engineering, life, physical, & social science, community & social service, education, training, & library, arts, design, entertainment, sports, & media, healthcare practitioners & technical, healthcare support, protective service, food preparation & serving related, building & grounds cleaning & maintenance, personal care & service, sales & related, office & administrative support, farming, fishing, & forestry, construction & extraction, installation, maintenance, & repair, production, transportation & material moving.
