What *has* happened is the massive thousand-fold rise in the number of people *diagnosed* with *some* anaphalactic reaction to peanuts and a zillion other irritants. When more people get *informed* there is a risk, the risk gets wildly exaggerated because of medical liability to any medical provider that does not address the completely-consistent-not-rising remote possibility of fatal reaction. And that translates into sales of expensive epi-pens from the company that conveniently funded the first and oft-cited major study into peanut allergy. And keeps funding other shoddy whitepapers on the topic. And keeps raising prices.
These guys are thieves. Those people are fools. Nothing new under the sun.
