How is one to rationally explain the Democrats' belief that the government taking over another one-sixth of the American economy is a good thing?
The answer is religion.
Given the huge economic failures that the left itself attributes to Medicare and Medicaid and given the economic collapse or near collapse of these systems in other countries, the left's prescriptions can only be explained in one way: The left has made its views a form of religion.
Most individuals on the left are not religious, but virtually all people, secular and religious, liberal and conservative, yearn to believe in dogma, i.e., absolute beliefs that transcend reason. For people on the left in Europe, the United States and elsewhere, belief in the state -- the notion that the state can do a better job at helping people and making a good society -- is one such dogma. This applies especially to educating the young and to health care.
Examples of left-wing dogmas that transcend reason are as numerous as any religion's catechism. One example is the belief that men and women, boys and girls, are basically the same, that the vast majority of characteristics we ascribe to male and female natures are in fact socially induced. This irrational dogma was virtually universally believed and taught by the left-wing faculty when I attended college, and remains so today.
Another is the belief that manmade carbon dioxide emissions are heating the world to the point of imminent worldwide catastrophe, including island nations disappearing underwater, mass starvation, inundation of the world's major coastal areas and much more. The fact that the world has been getting colder for the last eight years is as irrelevant to most people on the left as the absence of archaeological evidence for the biblical exodus is irrelevant to believing Jews and Christians. That includes me; I do not believe in the Hebrew exodus from Egypt because of scientific evidence, but because of faith. But unlike the left's belief in manmade carbon emissions leading to unprecedented and calamitous heating of the planet, I admit my belief is a leap of faith. And my belief in the exodus will not ruin Western economies. In other words, my non-scientific belief in the Jews' exodus is innocuous while the left's non-scientific beliefs (though shrouded in scientific jargon and promulgated by scientists who put dogma over science) are forced on societies.
