"The art of economics consists of looking not merely at the immediate but at the longer effects of any act or policy; it consists in tracing the consequences of that policy not merely for one group but for all groups."
There are two clear and present dangers to liberty. One is known as the Left, and the other is the Right. They seek to use government to mold society into a form they seek, rather than the form that liberty achieves if society is left on its own.
We often hear that various government policies are justified because "the people want" this or "we want" that. This belief assumes that dissenting minorities don't matter at all. "We want" is usually nothing more than rank majoritarianism.
