Here's an observation from Canada. I take it as proven globally that single payer universal coverage health systems are the least expensive method per capita to provide quality health care. When that single payer is the government, as it Canada, a very interesting dynamic sets it--Canadians have repeatedly made it know that they support tax increases for health care! 

In our system, the single payers are the provincial governments (with significant federal money), and health care is a very large portion of each province's total budget. That means that provincial politicians are always struggling to keep costs down or get more money from the feds so they have more room to fiddle with the rest of their budgets. And yet, whenever health costs becomes part of an election campaign, polls consistently show a willingness on the part of citizens to accept tax increases for health care. Just imagine that--a populations consistently willing to accept tax increases for something!
