Birth Activism

Since my recent visit to the Bay Area, where I heard more than a couple folks refer to midwifery care being available only to "rich hippies," my brain has been swirling around the idea of needing to do more birth activism - not only specifically engaging in the fight for universal legality and licensure of midwifery (as it is now, it is legal/licenced in some states, alegal/unlicenced in others and in some, outright illegal), but also fighting for the midwifery model of care to be paid for by Medicaid - so all women can have true freedom of choice in their care regardless of where they live or what their insurance/lack thereof status is.
What do you think about that? I am interested in finding out if there is already an organization dedicated to this work so I can join them.
