Why are some countries rich and some countries poor?
Is it access to natural resources? Is it tax policy? A motivated work force? These are important, but not determinative. The answer is deceptively simple - it's what's in our heads: knowledge.

Such an environment requires freedom, and intellectual property rights -- which is why the freest and most legally objective societies are the most prosperous. In five minutes, economist George Gilder explains why.
