Ryanair CEO does not believe in investment science

The on-line business tabloid, Business Insider, just gave an airing to Michael O'Leary, the CEO of Ryanair, who lambasted the scientific community for saying there is man-made climate change. He made the following shockingly ignorant accusation:

It is absolutely bizarre that the people who can't tell us what the f***ing weather is next Tuesday can predict with absolute precision what the f***ing global temperatures will be in 100 years' time. It's horses***.

The original interview was carried on the Irish Independent newspaper.

According to Wikipedia, Mr. O'Leary has a business degree from Trinity College, Dublin. OMG, what do you teach business students in Dublin? I imagine something like:

Don't believe those people who tell you to buy stocks for the long run. If they can't tell you what the f***ing stock price is next Tuesday, it is absolutely bizarre that they claim they can predict with absolute precision what the f***ing return on equity will be in 100 years' time. It's horse***.

So, Mr. O'Leary just called out the research of Jeremy Siegel, Burton Malkiel, and mainstream economists and business school professors as well as the investment management community for peddling non-sense.
