because the systems that sustain human life have been pushed to a dead end, to such an effect that very few benefit from the status quo, and such an immense amount of people, tens of millions of people have suffered incalculable harm just so solitary individuals can make slightly more money, year over year, even though they already make wildly greater amounts of money than all of the people who suffered agonizing pain, horrific disease, and death itself, in order to secure the slight increase of wealth in the pockets of people who could easily pay for the medical procedures to save their own lives, while tens of millions are senselessly tortured by the system with debt, struggle, strife, disrespect, and a lack of personal dignity.  they don't care about the life of the ceo because the ceo's only obligation, is to the shareholders and not the patients his corporation serves.  they don't care about the life of the ceo, because his death is just a drop in the bucket, compared to all the people who die annually, because the corporation decides that saving their life is *unprofitable*. and they don't care about the ceo's life because he has no national pride, no cultural bond, no tribal honor. he's an integer, a green number floating in the matrix, a nobody with no blood, no soil, no nation, no pride, no honor..  he extinguished the value of his own life first, mangione just stopped his body from functioning in such a way that he missed work the next morning.  corporate america doesn't value the life of this ceo man, and they never did.  they rely on us for that, maybe they should pay us to value their lives if that's what they want someone to do, because it sure as hell ain't their job, or else they'd be doing it, instead of treating us like slaves expected to worship them like gods for whatever reason.
