What a bunch of misleading propaganda.  We have a single payer system, its called Veterans Health Care.  Do you really want government bureaucrats deciding your health care issues??   Do you really want to long lines, long waits and less than adequate care as the veterans are getting??  Thank Trump that veterans can seek private care funded by the veterans administration.   
Do we want Canadian Health Care because its a single payer system??  Then why do Canadians flock to the US to get adequate private care when they have a critical issue?
We need a little applied common sense, not theoretical postulation which never works.
