Poor article in my opinion. As soon as I saw the "Individual’s Sensitivity Vector" which was literally just a single row matrix of undefined variables, I closed it. That matrix added absolutely no value to either the equation or the article. It was there purely to make the article look more scientific. And the article was not scientific at all. Your white vs. blue collar happiness assertion was unsubstantiated aside from anecdotal evidence. Adding pointless equations with "fancy" notation does not make anecdotes more reliable as evidence.
