The animus of these well-off liberals toward tax cuts and their sense of impending doom when such cuts are contemplated suggests they have been seduced by the idea that the government is the centerpiece of the American experience and the source from which all blessings flow. American liberals believe government has a duty to control all available resources to achieve fairness and equity throughout society. They are convinced the government must suppress people's selfish impulses to keep more of their earnings than they need. However, it is basic to human nature that people will not voluntarily yield the fruit of their labor for distribution to others in terms of some intellectual elitist's idea of what is just. They may be cajoled, propagandized and manipulated into doing it for a while, but in time they will rebel against it.
Compulsory compassion has no soul.
Self-sacrifice is not a proper engine for driving an economy. Human beings, as a derivative of the instinct to survive, are innately driven to act in their own self-interest. Any government or institution that runs head-on against the grain of this basic human drive is doomed, sooner or later, to fail.
