Libertarians warned for years that government is force, that government always grows and that America's police have become too much like an occupying army.
We get accused of being paranoid, but we look less paranoid after heavily armed police in Ferguson, Missouri, tear gassed peaceful protesters, arrested journalists and stopped some journalists from entering the town.
Drones -- unmanned flying machines -- will soon fill our skies. They conjure up fears, especially among some of my fellow libertarians, of spying and death from above.
These fears aren't groundless. President Bush approved the use of armed drones against suspected terrorists overseas, and President Obama vastly increased their use. Drones have killed thousands of people in places such as Pakistan and Yemen, countries against which we have not declared war.
If I drive across a U.S. border, I expect to stop at a Border Patrol checkpoint. But imagine driving to the grocery store, or Mom's house, well inside America, and being stopped by the Border Patrol. Many Americans don't have to imagine it -- it's how they live.
I'm the underachiever in my family. My parents also produced Harvard Medical School research director Thomas Stossel. Mom called him the one who had "a real job."
For years, my brother annoyed me by not embracing the libertarianism that changed my life. It bored him. He was comfortable in his Harvard cocoon.
But then he realized that the anti-capitalist activists who fight with me on my TV show are also the people who make life more difficult for doctors, and for patients who want cures.
I want the police to be better armed than the bad guys, but what exactly does that mean today?
"Tea party members don't think there's a federal role in transportation!" complained Sen. Sherrod Brown, D-Ohio, last week, near the site of a $5.8 million highway project.
Wars, plane crashes, mass murder -- it's easy to report news that happens suddenly. Reporters do a good job covering that. But we do a bad job telling you about what's really changing in the world, because we miss the stories that happen slowly. These are usually the more important stories.
Recently, President Barack Obama was mocked for saying: "The world is less violent than it has ever been. It is healthier than it has ever been. It is more tolerant than it has ever been. It is better fed than it's ever been. It is more educated than it's ever been."
There's capitalism, and then there's "crapitalism" -- crony capitalism.
Capitalism is great because it lets entrepreneurs raise money so they can scale up and get their products and services to more people. If there is free competition, innovators with the best ideas raise the most money, and the best and cheapest products spread far and wide.
But it's crapitalism when politicians give your tax money and other special privileges to businesses that are "most deserving of help." Often those businesses turn out to be run by politicians' cronies.
Reporter Sharyl Attkisson's story sounds familiar to me: A major network got tired of her reports criticizing government. She no longer works there.
Ray Kurzweil -- inventor of things like machines that turn text into speech -- has popularized the idea that we are rapidly approaching "the singularity," the point at which machines not only think for themselves but develop intellectually faster than we.
At that point, maybe we no longer talk about "human history." It will be "machine progress," with us along for the ride -- if machines keep us around. Maybe they'll keep us in a zoo, like we do with our monkey ancestors.
