Free prenatal and neonatal care seems like an obvious first step. It's literally taking care of the unborn and babies, so they have a healthy start to life. (I similarly believe education, school breakfasts and lunches, and pediatric care should be free.)
We could sidestep all the drama by letting anyone who meets the academic qualifications attend public universities and colleges without tuition (or at least an insubstantial fees). We might actually end up with a system like we had 75 years ago… but with less overt racism and sexism.
