Because one wage earner cannot do housework or child rearing or other behaviors now(as they are working another job), wouldn't that cause a roughly 1:1 ratio of missing worker to demand for a new job to take care of the labor necessary? e.g. No time to cook, so buy more food on the go, no time to clean, so buy labor to clean, no time to organize home, buy labor to organize, etc.?
That's correct, but none of those three people would then make as much money as the original single wage earner. And the couple wouldn't be getting ahead nearly as much as one would hope, since they have to pay for all that extra labor.
