i worked in a Goverment healthcare setting for a while (veterns administration), and here are some things that happen if the government takes over healthcare:
lazy docs cause there is ZERO incentive to see more people
6-12 month waiting lists
endless paperwork, then more paperwork
doctors are filling in forms and doing even more paperwork (paperwork is 80% of their time, and patients 20%)
basically, it was the worst case senario and the most inefficient thing i ever been involved with, beuracrats should be kept far far far away from healthcare.
