CEO of UnitedHealthcare was shot dead by person who deemed company's behavior is unacceptable. Horrible case, I am in no way defending it, but I believe everybody understands the motivation behind. If system cannot protect its citizens from predators then some folks tend to protect or avenge themselves or closed ones.
This was by far the most extreme case I've heard in long time. If similar things, maybe less drastic but very personal would be happening to many of those sociopathic greedy folks at helm responsible for vast damages, they would take note. But yeah if nothing really happens, once you have no morals and eternal greed who is there to stop you.
