"But they are free to study--to read, to improve their minds!" we protest. Minds are not vats to be filled eternally with more and ever more supplies. It is _use_, large, free, sufficient use that the mind requires, not mere information. Our college girls have vast supplies of knowledge; how can they use it in the home? Could a college boy apply his education appropriately to "keeping house"--and, if not, how can the girl? Full use of one's best faculties--this is health and happiness for both man and woman. But how about those other people's wages?--will be urged. Productive labour adds to the wealth of the world, it does not take away. If wealth were a fixed quantity, shared carefully among a lot of struggling beggars, then every new beggar would decrease the other's share. To work is to _give_, not to beg. Every worker adds to the world's wealth, increases everyone's share. Of course there are people whose "work" is not of value to anyone; who simply use their power and skill to get other people's money away from them; the less of these the better. That is not productive labour. But so long as we see to it that the work we do is worth more than the pay we get, our consciences may be clean; we give to the world and rob no one. As to the immediate facts that may be alleged, "overcrowded labour market," "over-production," and such bugaboos, these are only facts as watered stock and stolen franchises are facts; not economic laws, but criminal practices. A temporary superficial error in economic conduct need not blind us to permanent basic truth, and the truth which concerns us here is that a human creature must work for the health and power and pleasure of it; and that all good work enriches the world. So the girl need not stay at home and content her soul with chocolate drops lest some other girl lose bread. She may butter that bread and share the confections, by her labour, if it be productive. And by wise working she may learn to see how unwise and how unnecessary are the very conditions which now hold her back. At present she is generally held back. Her father will not allow her to work. Her mother needs her at home. So she stays a while longer. If she marries, she passes out of this chapter, becoming, without let or change, "the lady of the house." If she does not marry, what then? What has father or mother, sister or brother, to offer to the unmarried woman? What is the home to her who has no "home of her own"?
