unfortunately, it's not just a dollars and cents issue. putting the decision of who gets care and who doesn't in the hands of a board of directors carries all kinds of baggage. this idea that it's an objective decision based on maximizing profit is far too kind to the system. rather, you also have to take account of things like racial biases, personal favours and every other kind of corruption you could possibly imagine.
and, that's the irony in the propaganda. the right talks about collectivist health care systems as these centralized bodies that have the power to make decisions that will affect your lives. in truth, that's the system that america already has. most other advanced countries (like canada) have the concept of universality and refusal of treatment worked into their legislation - and in some cases it's even in the constitution.
the eugenics death councils are the insurance companies. and, they exist essentially nowhere else in the world.
