How would it work? Maybe I'm wrong, but once wage goes up there'll be prices growth for housing, daycare and other related things because more families is now able to afford it. It's simply the supply-demand equilibrium. So raising a single earner wage does not seem to do anything good, maybe without decreasing at the same time wage for the second earner (which is unacceptable for obvious reasons).
