Take King County Medic One as an illustrative example. The citizens of King County pay $0.30 per $1000 of assessed property value per year. The county government began collecting this levy in 2007 and has never exceeded the $0.30/$1000 rate. The levy completely funds Medic One's operations and the residents of King County are not charged a fee for ambulance service there. In the 5 years it has been in operation it has generated over $600 million despite the fact that the typical resident of King County probably only paid around $85/year for Medic One services (according to
NAR data the median home price in the Seattle-Tacoma-Bellvue metro area was $285,000).
Imagine if this program expanded to include the entire population of Washington. You could provide a robust, professional level of service to the entire geographic area at a much lower cost to each individual person. I don't see why this model couldn't be reproduced in each of the other 50 states.
