I don`t know about PT Barnum but John Ringling, his partner, had one helluva house in Sarasota, FL and has one of the most amazing art collections ever seen outside a major world center. In the 1920s he was as rich as Rockerfeller and Vanderbilt. I understand he lost it all in the stock market crash of 29....o, wait the college educated guys lost it all then too....oh, and in the crash of 2000.....
Education and common sense can peacefully co exist.
