Yeah I often see people discussing minimum wages and living wages, this was a different concept I stumbled upon for people to think about, which makes sense for society to consider because if workers have families they're not simply trying to earn a "living wage" (enough for them) but also enough for kids and/or spouse, etc.

family wage: enough to support a whole family by one breadwinner (traditionally thought of as an individual male; even with dual breadwinners you could still have an idea of how much a "family wage" would be that pays for the costs of the whole family)

living wage: enough to support an individual

minimum legal wage: legally allowed minimum to pay per hour (I don't know how common it has been for a minimum wage to be enough to raise a family)
