There's more than one kind of smart. I'm sure you know this to be true, which is why I'm puzzled that you seem so hung up on it.

I am of the opinion that having a building full of head-in-the-cloud brainiacs chipping away at hard problems in medicine, nanotech, industrial chemistry, etc will do more good for society than having a building full of the meanest, savviest businessmen brainstorming new innovative ways to trick people into buying comparatively poorly priced insurance / advertising / savings plans. Due to the non-excludability of scientific progress, we have an economic system designed to incentivize the latter at the expense of the former. That's a bug, not a feature.

Markets are very good at sniffing out and rewarding some kinds of value creation. They're not so good at sniffing out and rewarding other kinds of value creation and sometimes they create perverse incentives that are downright terrible. There are enough instances of this happening that I don't think it should be controversial to demand that "markets know best" philosophies should only be taken seriously if they come with a string of conditions for (at the bare minimum) identifying dysfunctional markets and rejecting their conclusions in such cases (e.g. Enron's rolling blackouts, pay-for-service health care incentivizing longer wait times, the Chinese Businessman strategy, Ponzi schemes, etc). "Markets know best" should never be taken as an article of faith, especially if you identify as a libertarian.

Libertarians philosophers that have won respect from the academic community (self-test: name 3, excluding Ayn Rand, otherwise you have homework to do) know how to qualify their arguments. "Markets know best" is a conclusion to be made (or not) under specific circumstances for specific reasons. There is no branch of libertarianism I am familiar with that has both survived the competitive back-and-fourth of the philosophical community and managed to uphold "markets know best" as a tautology. If you're taking "markets know best" as an article of faith, I would recommend examining this foundation for cracks. The most popular one (and the one I "fell" for during my libertarian phase) has to do with using a transaction-centric model for value creation. There are others. Perpetual vigilance is the only defense.

Sorry if I've read too much into your opinion, but it seems very similar to one that I used to hold and I'd be remiss if I didn't point that out.

Honestly I think you're wasting your time - you can't argue with a teen-at-heart who's channeling Ayn Rand. All of the ingredients are there - the narcissism, the arrogance, the reflexive assault on anyone perceived to be a threat (professors, advisors, anyone with wisdom or experience or authority) to his decisions (to give up his intellectual pursuits) or his perception of himself as a brilliant mind who pierces through all the bullshit the lesser minds that surround him are taken in by. He's the only one 'brave' enough to say and to see that deep thought or high-minded goals or hope that society could be better or anything other than a short-term cost benefit analysis where value is measured only in dollars is moronic. These comments like his are toxic in any intelligent discussion and don't really deserve a thoughtful response like yours.

This is a great summary of the pitfalls of laissez-faire economics. Do you have a blog where you write about your political/economic beliefs? Also, what books/resources have you found most useful in attaining a more accurate perspective on the way economies actually work?
