Well, it does give you a number of "don't do this!" or "watch out for this sort of person" or developments lessons, and the bit on laws for a society at our level of "development" is priceless:

"Did you really think that we want those laws to be observed?" said Dr. Ferris. "We want them broken. You'd better get it straight that it's not a bunch of boy scouts you're up against - then you'll know that this is not the age of beautiful gestures. We're after power and we mean it. You fellows were pikers, but we know the real trick, and you'd better get wise to it. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals, one 'makes' them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws. Who wants a nation of law-abiding citizens? What's there in that for anyone? But just pass the kind of laws that can neither be observed nor enforced nor objectively interpreted-and you create a nation of law-breakers and then you cash in on the guilt. Now that's the system, Mr. Rearden, that's the game, and once you understand it, you'll be much easier to deal with."

But, yeah, little positive that'll tell you what to do, the "invent a much better mousetrap" and, ahem, connect up with a market that needs it would seem to be a lesson is so obvious it hardly needs to be taught. But it does, as the author emphasizes, and there are many many books now that are really focusing on that.
