Sanders promoting a single payer system displays a blatant ignorance of economics and the inability to understand single payer system is a prescription for disaster.
One only need look to Canada where everyone shares the same access to a stunted version of healthcare. CTV News reported wait times for doctors appointments in the Canadian healthcare system sometimes takes up to 20 weeks….more than doubled the wait times in 1993. 
“The Fraser Institute, a Canadian public policy think tank, estimates that 52,513 Canadians received non-emergency medical treatment in the U.S. and other countries in 2014, a 25 percent jump from the roughly 41,838 who sought medical care abroad the previous year.
In citing those numbers in its 2015 report, “Leaving Canada for Medical Care,” the organization said difficulties in obtaining timely medical care at home is, increasingly, leading Canadians to seek it abroad. “It is possible [they] may have left the country to avoid some of the adverse medical consequences of waiting for care, such as worsening of their condition, poorer outcomes following treatment, disability, or death,” the report says. “Some may leave simply to avoid delay and to make a quicker return to normal life.” 
The Huffington Post, in an article in 2014 reported, “Protracted wait times may also result in potentially treatable illnesses and injuries becoming chronic, permanent, debilitating conditions. In such circumstances, requiring patients to accept inordinately long waiting times, without the opportunity to seek alternative treatment denies them their basic human right to lead healthy lives (as recognized by the Supreme Court in 2005).” 
Looking at the Canadian socialized, ie, single payer, healthcare system, one might, should they have the ability to critically analyze the deadly consequences of a single payer system, realize that the single payer system is nothing more than a death watch for those unable to receive adequate medical care.
The one thing Sanders fails to mention, is that politicans and the establishment elites will not have to participate and therefore never have to suffer the potentially deadly consequences of a single payer system….WFM
