I used to think "capitalism" was a miracle machine.

It is absolutely necessary, yes, but it is not sufficient. IE, you can give capitalism to African tribesmen and they won't be building rockets to the moon anytime soon, let alone farms or houses.

Capitalism, combined with a motivated people who have faith in God and are striving to bring God's kingdom to earth, is what is needed. Next to capitalism you need preachers and mothers and fathers and neighbors preaching the Word, and individuals who have turned their hearts and minds over to God, and a solid determination to make something amazing despite the hardships of the world.

In other words, you need Americans.
