Sixty-six billion dollars
That's how much Bayer just agreed to pay to acquire Monsanto in a deal which will potentially have tectonically negative consequences for the world and your longevity.
You don't need to be an ethics philosopher to see the significant moral hazard in the unholy marriage of a company that makes people very sick and a company that sells drugs to treat sickness.
A brief history of these two corporate giants
Bayer was founded in 1863 in Germany. A pioneer in the chemical and proto pharmaceutical industries they invented Aspirin and contributed to the industrial revolution in Europe. In 1925 in a nation impoverished by WW1 Bayer joined the IG Farben conglomerate, which has gone down in history as one of the most evil corporate citizens of all time, researching and producing chemicals like Zyklon B that enabled some of the most despicable war crimes in history.
It would be difficult to call the current iteration of the company evil based solely on their participation in WW2 70 years ago, however many still consider it one of the least benign corporate citizens in the world because of it's Factor VIII scandal in the 1980's; when it turned out that a product of their's infected 6,000 hemophiliacs with AIDS they paid out a $600 million settlement and then outrageously proceed to continue to sell the product in other international markets, infecting unwitting people around the world with the deadly virus. Today they hold over 60 thousand patents and have 82 branded products.
Monsanto needs little introduction, it's an American company founded around the turn of the 20th century that produced food additives like saccharin, caffeine, and vanillin.
They also produced the insecticide DDT, which can largely be credited for diminishing the blight of malaria epidemics around the world, but it (perhaps unfairly) was demonized by environmentalists and ultimately banned.
Monsanto's contribution to history that has perhaps earned it more infamy that any other is it's role in the production of Agent Orange; used by the US as a chemical weapon in the Vietnam war.
One of their most successful products Roundup, based on Glyphosate, is identified in an increasing number of recent studies as a serious threat to public health.
Today Monsanto remains one of the most hated companies in the world for it's role as a producer of GMO seeds and it's employment of draconian legal tactics to force farmers to use their products. Monsanto has been banned from at least 38 countries. Today they hold over 4000 patents and have 37 different brands.
I don't ascribe to the fringe conspiracy theories about the purposeful evilness of these companies; I think it's a combination of the perverse sticks and carrots that our globalized world offers in combination with the outgroup preference that a corporate culture engenders naturally amongst it's employees. Here's an interesting talk on how otherwise good people dehumanize others:
