Government spending reduces the capital that could be invested to serve consumers and to produce new employment opportunities.

Why is Netanyahu pushing war? Among several reasons, demonizing Iran reduces pressure on Israel to negotiate seriously with the Palestinians. Many Israelis prefer building Jewish settlements on Palestinians' land instead. Moreover, Israel's rulers oppose any development-such as an Iranian-U.S. detente-that could diminish Israel's U.S.-financed hegemony in the region. War with Iran would be a catastrophe all around. Netanyahu and his hawkish American allies-the same people who gave us the disastrous Iraq war and ISIS-must be repudiated.

We think of prices as simply the notation of how much we must pay for things. But the price system accomplishes far more than that. Hundreds of millions of people buying and selling, and abstaining from buying and selling, generate a system of signals - prices to producers and consumers about relative scarcities and demand. Through this system, consumers can convey to producers their subjective priorities and entrepreneurs can invest accordingly.

Perhaps the deterioration of American education is illustrated by the high correlation between the number of years a person has attended school and his inability to understand the words "the right of the people to keep and bear arms shall not be infringed." It is more likely, though, that those who interpret the Second Amendment to preclude an individual right to own guns are driven by their political agenda. Whichever the case, they do themselves no credit when they tell us that a simple, elegant sentence means the opposite of what it clearly says.

No matter how much the government controls the economic system, any problem will be blamed on whatever small zone of freedom that remains.

The draft is a monstrous violation of individual liberty, and even a good motive cannot make it otherwise. In a free society no one should be compelled to take up arms, or be forced to kill or risk being killed... But who can blame prospective volunteers from doubting that there is a threat from Iraq? The Bush administration has yet to make a persuasive argument to that effect.

Wealth comes from the production and exchange of goods and services. If someone efficiently produces a good that many people willingly trade their money for, he becomes wealthy.
