If 37 is an old fogey, then I am guilty.
But in my business it seems like every 5-10 years a new crew of MBAs/PhDs come in and think that they are smarter than everyone who has ever walked the Earth. The last crew almost blew up the financial system since the housing market never went down.
Were they smart and have good ideas? Of course. But there are always limits, especially when the ideas are on the newer side.
