But who informs the voters? Who funds those incredibly insane fearmongering commericals and campaigns that appear before elections?

A friend in California paid triple in deductables than the Australian Medicare tax deducted from my annual salary, and we earned about the same income. I know you're aware of the insanity of this, but what hinders us from acknowledging the poorer countries like Argentina, Nicaragua, Costa Rica, etc., offer healthcare to all. Yet, the US can't figure out how to implement public healthcare? It doesn't make sense.
