most economists spend their lives trying to make sense of irrelevant data. it is no surprise that their findings are senseless and devoid of any scientifc rigor. if you go to any economics department, then you will see that most econ "researchers" are just bootleg quasi-mathematicians who weren't smart enough for physics or engineering.
economics is on the same level as astrology or sociology when it comes to usefullness. a good example can be found in the fenenace industry. renaissance technologies, the most profitable hedge fund in existence, only hires physics/math/CS PhDs. the firm has a rule against hiring economists because it was smart enough to realize that all of them are idiots. what has not hiring economists led to? 35% average annual return for the past 30 years. how sad is it that econolosers get shut out of their own field.
