You cannot understand the left if you do not understand that Leftism is a religion. It is not God-based (some Left-wing Christians' and Jews' claims notwithstanding), but otherwise it has every characteristic of a religion. The most blatant of those characteristics is dogma. People who believe in Leftism have as many dogmas as the most fundamentalist Christian.
One of them is material equality as the preeminent moral goal. Another is the villainy of corporations. The bigger the corporation, the greater the villainy. Thus, instead of the devil, the left has Big Pharma, Big Tobacco, Big Oil, the "military-industrial complex," and the like. Meanwhile, Big Labor, Big Trial Lawyers, and, of course, Big Government are leftwing angels. And why is that? Why, to be specific, does the left fear big corporations but not big government? The answer is dogma -- a belief system that transcends reason. No rational person can deny that big governments have caused almost all the great evils of the last century, arguably the bloodiest in history. Who killed the 20-30 million Soviet citizens in the Gulag Archipelago -- big government or big business? Hint: There were no private businesses in the Soviet Union. Who deliberately caused 75 million Chinese to starve to death -- big government or big business? Hint: See previous hint. Did Coca Cola kill five million Ukrainians? Did Big Oil slaughter a quarter of the Cambodian population? Would there have been a Holocaust without the huge Nazi state?
Whatever bad big corporations have done is dwarfed by the monstrous crimes -- the mass enslavement of people, the deprivation of the most basic human rights, not to mention the mass murder and torture and genocide -- committed by big governments.
How can anyone who thinks rationally believe that big corporations rather than big governments pose the greatest threat to humanity? The answer is that it takes a mind distorted by leftist dogma. If there is another explanation, I do not know what it is.
Religious Christians and Jews also have some irrational beliefs, but their irrationality is overwhelmingly confined to theological matters; and these theological irrationalities have no deleterious impact on religious Jews' and Christians' ability to see the world rationally and morally. Few religious Jews or Christians believe that big corporations are in any way analogous to big government in terms of evil done. And the few who do are leftists.
That the Left demonizes "Big Pharma," for instance, is an example of leftwing thinking. America's pharmaceutical companies have saved millions of lives, including millions of leftists' lives. And I do not doubt that in order to increase profits, they have not always played by the rules. But to demonize big pharmaceutical companies while lionizing big government, big labor unions and big trial law firms, is to stand morality on its head.
There is yet another reason to fear big government far more than big corporations. ExxonMobil has no police force, no IRS, no ability to arrest you, no ability to shut you up, and certainly no ability to kill you. ExxonMobil can't knock on your door in the middle of the night and legally take you away. Apple Computer cannot take your money away without your consent, and it runs no prisons. The government does all of these things.
Of course, the left will respond that government also does good and that corporations and capitalists are, by their very nature, "greedy."
To which the rational response is that, of course, government also does good. But so do the vast majority of corporations, private citizens, church groups, and myriad voluntary associations. On the other hand, only big government can do anything approaching the monstrous evils of the last century.
As for greed: Between hunger for money and hunger for power, the latter is incomparably more frightening. It is noteworthy that none of the twentieth century's monsters -- Lenin, Hitler, Stalin, Mao -- were preoccupied with material gain. They loved power much more than money.
And that is why the left is much more frightening than the right. It craves power.
