I'd argue that that's the wrong goal. Ideally, families can afford to live off of one salary so that mothers could choose to continue to care for their children if they wanted to do so.

Currently, very few families are privileged enough to live off of one salary. Both parents need to work in order to make ends meet.

I'm not saying it's an easy problem to solve, or that free childcare isn't a good interim solution. But important to keep the end goal in mind.

The government can set up free child care as it has already set up other similar programs.

How would the government make it so that a single salary can provide for a family? Wouldn't this require massive interference with the economy?
