I guess if you can enjoy the benefits of a free market while not spending a dime to insure the free flow of trade and ideas then you can consider yourself more efficient. The EUROs have been free riding on defense since 1945. Too bad none on this list has done squat for the freedom of anyone but themselves.
You are correctomundo about that. Look at Iceland - we're pulling out of Iceland in the next few months and they're whining about who will pay to provide ocean search and rescue operations if the US Military isn't there to do it for them.
Socialists are all freeloaders.
