A couple points:
Alternatives to patient-present doctor-mediated health care to cover the 80% case in which doctors are expensive overkill; some combination of telemedicine and nurse-practitioners.
We have police departments and we have fire departments. We should have "nurse departments" that are clinics but much more structured as are fire and PD services for each given area.
(I know there is a grey version of this with EMT/clinics/hospitals etc... but this is something that could be made better.)

Modern logistics-driven solutions for inexpensive high-quality child care.
We talk a lot about "getting more women in tech" for example...
Getting more women JUST TO BE ABLE TO WORK involves insuring child care!
Sending a kid to child care full time costs MORE than many women can make per hour! Its ridiculous.
If you have ever tried to look for child care services on Care.com or otherwise, sitters all want ~$25/hour in the bay area.
