Paraphrasing (25th paragraph)
Text
There is no palatable alternative to free economies and free trade. A market economy isn't simply a place where people provide goods and services in the pursuit of profits — not that there's anything wrong with that. Market competition is also a discovery process; a way of learning things we wouldn't otherwise know, and which we learn from people we may have never met. It is that knowledge that makes us more productive, wealthier, healthier, and better able to protect our world. The ability to reason and innovate is one of mankind's greatest gifts. Yet the only way to realize that potential, to get at the knowledge that improves our lives, is through an open market system where people are allowed to compete to satisfy the wants and needs of others. We need, in other words, the freedom to trade. Any barriers that short circuit that process leave us with a smaller pool of talent and ideas, and thus leave us poorer. The blessings of free markets at home are undeniable; trade merely widens the circle of opportunity to people who's previously been excluded.
