Political scientist Edward Banfield, in his book The Unheavenly City, responded to the dilemma of why some people commit crimes and why other people don't, stating that criminals act unwisely because of their "orientation toward the future" consisting of their "inability to imagine a future", combined with their "inability to discipline" themselves "to sacrifice present for future satisfaction". By making this distinction of why criminals commit crimes he has also told us why liberals, in the realm of politics, ruin everything they touch: They have no concept of a future, and they are unable to sacrifice today for rewards in the future. They just do things, and nearly always their actions involve spending other peoples' money. They are impulsive and rash in their actions and in their legislation (remember how urgent the stimulus was and how they forced Obamacare down our throats without allowing any Republican input, and how they coerced doubting Democrats to vote for the destructive legislation without delay or debate)? Liberals commit political and legislative violence when they have their way with policy, and the entire nation ends up eventually paying a heavy price for their ill-considered actions, as we are now seeing with our unbelievable debt and the fact that nearly all states face financial crises, if not outright bankruptcy.
Banfield's theory would also explain why liberals cause such pain and suffering: they are unable to apply principle to their actions and can't visualize the future and the down-side of their actions (they feel good about handing out welfare to the poor, and generous retirement packages to government employees, without considering that welfare recipients will get trapped in dependency and that government retirees may one day be left with a reduced retirement when the money runs out, as we are currently seeing). They claim their compassion causes them to be overly kind in their givings, but actually it's because they are honestly unable to comprehend the future results of their actions and because it's not their money they are doling out.
At present we are facing an increasingly violent response from liberals as they face an end to the heyday they've had and the promises they've made for the last 40 years. The mobs in Wisconsin show where all states, cities, and eventually the federal government are headed now that we have responsible adults in charge of policy, and the liberal juveniles are objecting to having their lavish spending policies reversed. Our nation is nearing destruction, and still liberals cannot see the over-reaching they've done and the misery they've caused. We must stand firmly behind all politicians who are serious about reducing spending and reducing the size and intrusiveness of government, or we all will face a future that is bleak and uncomfortable, and our children will never know the joy of living in a free and prosperous nation.
