It all started back in 2007 when Mylan ( NASDAQ : Mylan [MYL] ) bought the EpiPen patent and turned a previously inexpensive decades-old emergency allergy drug, into a pricey must-have. Since 2007, the EpiPen price went up from $56.64 to $317.82 per piece, demonstrating a price increase of over 460%. Interestingly, the salaries of Mylan's CEO Heather Bresch as well as some other managers have dramatically increased over the exact same period. NBC News has reported Bresch's compensation growing by 670% in the past 8 years: from $2.453,456 in 2007 to $18,931,068 in 2015.
